Run the applet entitled Simulating the Probability of a Head with a Fair Coin 10 times with n = 2, resetting between runs, to simulate flipping two coins 10 times. Count and record the number of heads each time. Let x represent the number of heads on a single flip of the coins.
a. What are the possible values of x?
b. Use the results of the simulation to find the probability distribution for x in table form.
c. Explain why the probability of exactly two heads should be close to .25.
