Part 1 - Discussion Questions

1. How many heads did you predict to occur out of 10 tosses of the single coin (within one ʻtrialʼ?)? _______

(Hypothesis A)

2. How many heads did you predict to occur out of 100 tosses? _________

(Hypothesis B)

3. Did you ever obtain the expected results in any series of 10 tosses? ________ If yes, for how many trials?

4. Are the expected results (hypothesis) and observed results (data in table) for 100 tosses the same? Can

they be the same? Explain

____________________________________________________________________________________

5. How does increasing the number of tosses affect the amount of difference from the expected value?

(How does increasing the number of trials affect obtaining the expected results?)

Part 2 - Hypothesis:

If you ﬂip two coins 60 times, then youʼd expect both coins to land on heads _____ times, both to land on

tails _______ times and one to land on heads and the other coin to land on tails ______ times.

Part 2 - Procedure

Trial

H 1 H 2

H 1 T

H 2 T

T 1 T

Coin #1 =

Totals

1. Repeat the procedure in Part 1, using two coins of different value(preferably different colors, too). Record

the results in Table 2, indicating “H

” if both coin landed heads, “H

” if the coin #1 landed heads and coin

#2 landed tails, and so on, as shown in the Table above.

2. You should perform trials 1-3 and your partner should perform trials 4-6. Make sure you are using the

same values of coins. Remember: each trial =10 tosses.

Part 2 - Discussion Questions

1. In what fraction of the total number of tosses did heads for both coins appear? _______________

Tails for both coins? ____________ Heads for one coin, and tails for the other? ______________

2. Compare your results to your hypothesis. Why or why not were the actual and expected values the same?
