2. A child of a specific set of parents has a 0.2 chance of having type O blood. Suppose these parents have 4 children. Let X = the number of children having type O blood. a) Verify that this is a binomial setting and write the notation (B(n,p)). b) What is the probability that exactly 2 of the children have type O blood? c) Make a probability distribution table for X = 0 to 4. Verify that the sum of these probabilities is 1. d) Construct a histogram of the probability distribution. (Please check with your instructor on how to submit your work.) a )
