The probability of having blood type A is 0.4. Choose 4 people at random and let 7 be the number with blood type A. is a binomial random variable with n = and p = 9 = Now use the binomial probability formula, P(r) =n Crp qn T, to complete the chart below. Enter the simplified for of the exponents. (Example: If n - T = 4 -1 = 3, you would enter 3.) Do not round any values.
