Flip a coin 4 times. Recall from class that we found the probability distribution for the number of heads as well as the mean and standard deviation o of X4. Using the probability distribution we found in class, determine the probability that the number of heads is within 1 standard deviation of the mean. That is, the probability that μ-o≤x≤μ+o.
