Activity: Tossing 5 coins
Conduct a small experiment on probability distribution by tossing 5 coins. Perform the
experiment by tossing 5 coins 20 times, Observe the number of heads that will occur. The
possible values of X or the number of heads in 5 coin tosses are 0,1,2,3,4, and 5. Keep track
of the number of times each outcome occurred and complete the table below.

After the experiment, answer the following questions based on your observations.
a. Compare the approximate probability values and the actual probability values. How
can you make the approximate probability values very close to the actual probability
values?
b. What is then expected mean and variance of the random variable X? Use the actual
probability in your solution.
