As in the previous problem, a fair coin is flipped 76 times. If X is the number of heads, then the distribution of X can be approximated with a normal distribution, N(38, 4.4), where the mean (u) is 38 and standard deviation (6) is 4.4. Using this approximation, find the probability of flipping 42, 43, or 44 heads. You may use the portion of the Standard Normal Table below.

Question
As in the previous problem, a fair coin is flipped 76 times. If X is the number of heads, then the distribution of X can be
approximated with a normal distribution, N(38, 4.4), where the mean (u) is 38 and standard deviation (o) is 4.4.
Using this approximation, find the probability of flipping 42, 43, or 44 heads. You may use the portion of the Standard
Normal Table below.
