Suppose that a family has an equally likely chance of having a cat or a dog. If they have two pets, they could have 1 dog and 1 cat, they could have 2 dogs, or they could have 2 cats.
1. What is the theoretical probability that the family has two dogs or two cats?
2. Describe how to use two coins to simulate which two pets the family has.

this is what i put for #2:
2. Describe how to use two coins to simulate which two pets the family has.
I can use two coins to simulate which two pets the family has by letting heads represent how many dogs there are and letting tails represent how many cats there are.

- dan815

okay so Pet 1 is either a Dog or a Cat
and Pet 2 is either a Dog or a cat
you need to see what prob is it where they are both dogs or both cats

1/3 ?

- muscrat123

i mean 1/2 ?

- dan815

yes

- dan815

now with 2 coins instead of , dog and cat, u have heads and tails

- muscrat123

so the theoretical probability of there being 2 cats/2 dogs is 50%

- muscrat123

which is #1 s answer, yes?

"now with 2 coins instead of , dog and cat, u have heads and tails"
so what i put for #2?

- dan815

you repeat the same thing with heads and tails as dogs and cats

- muscrat123

i put this for #2
2. Describe how to use two coins to simulate which two pets the family has.
I can use two coins to simulate which two pets the family has by letting heads represent how many dogs there are and letting tails represent how many cats there are.

- dan815

okay, go on, u have to talk about what u do with those heads and tails

- muscrat123

^^^ hang on

- muscrat123

here, ill just post the whole thing

oh muscrat what u can do is, basically flip coins a bunch of times and see the probability u are getting 2 heads and 2 tails

- dan815

and over time it will be half the time for every 2 flips

- dan815

and u can talk about why this is happening by drawing a tree diagram, or using some other method to show why the theoretical prob is 50%

- muscrat123

what does that mean? how can i put that into an answer for something?

- muscrat123

im so confuzzled....

- anonymous

what lesson is this?

- muscrat123

7.03 on FLVS

- dan815

well you see in part 3) they are flipping coins 50 times and recording the data, they are trying to show you that the experimental probability will start to follow the theoretical prob

- muscrat123

the chart is what i did....

- muscrat123

@dreamio why?

- anonymous

cause i did the same lesson

- muscrat123

did u get a 100?

- anonymous

no i got a 15/20 haha but i know what i got right

- muscrat123

lol. PLZ HELP!!!!!!!

- anonymous

what question ?

- muscrat123

all of it.

- muscrat123

what ? did u get wrong/

- muscrat123

?*

- muscrat123

??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

- muscrat123

ANYBODY????????????

- anonymous

wait

- muscrat123

kk

- muscrat123

i need to give an answer

- imqwerty

hey can u guys switch on nd off ur qualified helper mode?

- muscrat123

SERIOUSLY?!?!?!?!?!

- anonymous

haha ok but i dont have number 5

- muscrat123

ok

- muscrat123

im sure ill b able to figure it out...probably

- anonymous

its from my experiment so dont forget to fill it in with your info

- muscrat123

is number 5 33% or did u put that and it was wrong?
numbers 4-6:
4. Based on your data, what is the experimental probability that the family has two dogs or two cats?
5. If the family has three pets, what is the theoretical probability that they have three dogs or three cats?
6. How could you change the simulation to generate data for three pets?

- anonymous

i didnt put that for 5 so i dont know sorry

- muscrat123

what did u pu tfor other questions?

- anonymous

it wont let me copy and paste

- anonymous

give me a minute im sorry

- muscrat123

ok its ok

- anonymous

1. What is the theoretical probability that the family has two dogs or two cats? 1/2
2. Describe how to use two coins to simulate which two pets the family has. For the stimulation heads will be cat and tails will be dog, so if you get something like two heads that will mean two cats .
4. Based on your data, what is the experimental probability that the family has two dogs or two cats? 27/50 or 54%.
6. How could you change the simulation to generate data for three pets? I would change the amount of coins to three.

- anonymous

got it?

- muscrat123

yea, can u get ur table on here? i have trouble with experimental and theoretical probability

- anonymous

Result Frequency
Heads, Heads 14
Heads, Tails 13
Tails, Heads 12
Tails, Tails 13
Total 50

- anonymous

that?

- muscrat123

yes!

- anonymous

haha well everyone's is different because its experimental but yeah thats what i got

- muscrat123

i got it now, do u think u can check over my answers b4 i submit it?

mhm one sec

- muscrat123

thx 4 ur help

- anonymous

you have an extra chart haha but everything else seems fine

- anonymous

oh nvm

- muscrat123

i know i just thought it would be good to show that. did u finish ur course?

- anonymous

um no i have to do the dbas and exams but i finished all the assignments

- muscrat123

im so far behind!!! it must be nice lol. im doing 2courses.

- muscrat123

got 118 to do in 3 days

- anonymous

im doing all my classes, and why three days
