sorry about the numbers im a little tired but i have to get this in

- anonymous

i understand. i shall do my best to help you.

- anonymous

thank you

- anonymous

your welcome. so how many H and T did u get total?

In your own words, describe two main differences between classical and empirical probabilities.
The difference between classical and empirical. The classical probability also assumes all the outcomes which are favorable to the reoccurrence.
Empirical is based on the observed by frequencies.
Gather coins you find around your home or in your pocket or purse. You will need an even number of coins (any denomination) between 16 and 30. You do not need more than that. Put all of the coins in a small bag or container big enough to allow the coins to be shaken around. Shake the bag well and empty the coins onto a table. Tally up how many heads and tails are showing. Do ten repetitions of this experiment, and record your findings every time.
Shake Heads Tails
1 6 10
2 8 8
3 9 7
4 9 7
5 6 10
6 7 9
7 8 7
8 9 7
9 7 9
10 12 4
I used 16 coins
The formula that I used was P (E) Observed Frequency of Specific event (f) = f
Sum of Frequency n
In my first count the probability of tossing a head was:
6/16=3/8
In my first count the probability of tossing a tail was:
10/16=5/8

thats the tails

- anonymous

for tails its 7.8

- anonymous

they are asking for just the heads

- anonymous

head is 8.1

- anonymous

is that the average

- anonymous

thats it added and divided im working on the average. so that i feel like im helping u and not jut giving u the answer what did u learn about average? any specific things?

- anonymous

i hate to be a pain but i have to see the work cause i have to show my work even on a discussion

- anonymous

what did u learn about averages? i'll how u the work. and sorry if im a little slow at helping but im in the middle of an exam and a 90 point assignment.

- anonymous

show*

- anonymous

we just started the average so this is my first turn around it

- anonymous

you haven't learned anything about it?

- anonymous

nope

- anonymous

to find an average you add all your numbers together and then divide it by the amount of numbers you added.
i did do your T for example.
10 + 8 + 7 + 7 + 10 + 9 + 7 + 7 + 9 + 4 = 78
now you count how many number you added together(which is ten)
78 ÷ 10 = 7.8
Therefore your average of T - 7.8
is that easier to understand?

- anonymous

So what i need to do is add all my heads #'s toger

- anonymous

after doing that i get 78

- anonymous

7.8 after dividing it

- anonymous

the H average is 8.1
6 + 8 + 9 + 9 + 6 + 7 + 8 + 9 + 7 + 12 = 81
divide 81 by the number of numbers you added together(which is ten)
81 ÷ 10 = 8.1
Therefore your average for H i 8.1

- anonymous

yes. you got it! (: did i help you to better understand this?

- anonymous

yes
but here is the instuctors example

- anonymous

6 of my repetitions came out to have exactly the same number of heads and tails
This did not happen every time because the outcomes occur and random.
I am using empirical probability
The average number of heads came out to be 11.8%
10+14+14+11+13+5+10+13+17+11=118/10= 11.8%
The average probability of getting heads is 59%
11.8/20=59%
I turned out that 59% of the time, the coin fell on heads. I thought that was very interesting because I expected it to be more equal,
The sample space for the outcomes of 3 coins are:
· HHH, TTT, HHT, TTH, HTH, THT, THH, HTT
1
8
· We are using the classical probability

- anonymous

now you see why im a little confused

- anonymous

so you need percentages?

- anonymous

yup

- anonymous

easy

- anonymous

remember what I just taught you?

- anonymous

ok

- anonymous

you are going to have to bare with me im also sick with the flu

- anonymous

take each average average. let do 7.8 so i dont confuse you
7.8 ÷ 20 = 39%
8.1
8.1 ÷ 20 = 405%

- anonymous

i know it doesnt look right. but it is. all you do is tak your average and divide that by 20.

- anonymous

no way! mee too!!! i had high fever all day yesterday! and its fine! i know how it is trying to do things that you dont understand in a deadline im jut glad i could help you(:

- anonymous

can you show me where i am supose to put the numbers

- anonymous

i have over 102 for the past 4 days and my vision is blurry

- anonymous

i had 103 yesterday and was throwing up all day. and put what numbers where?

- anonymous

6 of my repetitions came out to have exactly the same number of heads and tails
This did not happen every time because the outcomes occur and random.
I am using empirical probability
The average number of heads came out to be 11.8% was my next step

- anonymous

the bad thing is i have 12 different kinds of seziures

- anonymous

oh im sorry :( i hope u get better soon! and i dont understand the above :/ what are you talking about?

In your own words, describe two main differences between classical and empirical probabilities.

Put all of the coins in a small bag or container big enough to allow the coins to be shaken around. Shake the bag well and empty the coins onto a table. Tally up how many heads and tails are showing. Do ten repetitions of this experiment, and record your findings every time.
State how many coins you have and present your data in a table or chart.
Consider just your first count of the tossed coins. What is the observed probability of tossing a head? Of tossing a tail? Show the formula you used and reduce the answer to lowest terms.
Did any of your ten repetitions come out to have exactly the same number of heads and tails? How many times did this happen?
How come the answers to the step above are not exactly ½ and ½?
What kind of probability are you using in this “bag of coins” experiment?
Compute the average number of heads from the ten trials (add up the number of heads and divide it by 10).
Change this to the average probability of tossing heads by putting the average number of heads in a fraction over the number of coins you used in your tosses.
Did anything surprising or unexpected happen in your results for this experiment?
Write the sample space for the outcomes of tossing three coins using H for heads and T for tails.
What is the probability for each of the outcomes?
Which kind of probability are we using here?
How come we do not need to have three actual coins to compute the probabilities for these outcomes?
Respond to at least two of your classmates’ postings. Make sure you review their data and calculations and let them know if their probabilities seem accurate.

how many coins did u use?

16

here she is saying all the possible outcomes

- anonymous

In my first count the probability of tossing a head was:
6/16=3/8

- anonymous

ok. can u simplify that fraction anymore?

- anonymous

3/8

- anonymous

can u simplify 3/8 any further?

- anonymous

no

- anonymous

then that i your final answer

- anonymous

In my first count the probability of tossing a tail was:
10/16=5/8

- anonymous

no 5/8 w as i can go

- anonymous

i got confused after that

- anonymous

5/8 is your final answer. is cant be simplified anymore

- anonymous

it is the steps after that i get confused

- anonymous

no more steps. that the final fraction
