Working with binomial probability. A histogram is attached in a jpg format.
If the parents have 5 children, the number who have type O blood is a random variable X that has the binomial distribution with n=5 and p=0.25
a) What are the possible values of X?
b) Find the probability of each value of X. Draw a histogram to display this distribution. (Because probabilities are long-run proportions, a histogram with the probabilities as the heights of the bars shows what the distribution of X would be in very many repetitions.)
