There is a 25% chance that a randomly selected individual will have blonde hair. Suppose we randomly select 15 individuals from the population and see whether they have blonde hair. Let X denote the number of individuals in the sample that have blonde hair. (a) What is the distribution of X in conventional statistical notation? (b) What is the probability that at most 6 individuals in the sample have blonde hair? (c) What is the probability that at least 9 individuals in the sample have blonde hair? (d) What is the P(2 < X < 7) equal to? (e) How many individuals in the sample do we expect to have blonde hair? (f) What is the standard deviation of X
