Suppose we run an experiment where we flip a coin 3 times and record the number of heads that come up.  We run this experiment four times and find the average number of heads.  Approximate the probability that the average number of heads is greater than 2 (within, say, 5-10 percentage points). (Hint: CLT!)

Since either head or tail in each outcome, 1/2×4=1/8

Since the coin is flipped 3 times, 1/8×3

3/8

8÷3=2.66
