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

Best ResponseYou've already chosen the best response.0In 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

Best ResponseYou've already chosen the best response.0to 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?

Best ResponseYou've already chosen the best response.0the 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

Best ResponseYou've already chosen the best response.06 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

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.
