How do you solve this?

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

The probability of choosing 2 people with type A blood, out of a group of is 2. What is the probability of at least 3 of the 4 people having a blood type of A
