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. " is a binomial random variable with n and p Now use the binomial probability formula, P(r) -n Crp q"-T, 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. T Probability Formula P(r) 4 Co (0.4)( 0.6) 4 0.1296 c (0.6) 3 0.3456 2 4C (0.4)2 3 C3 3 0.1536 4 4C4 (0.4) (0.6) Interpret the Data 1. What does P(2) = 0.3456 mean? The probability of choosing 2 people with type A blood, out of a group of 4 is 34.56 + 1%. 2. What is the probability of at least 3 of the 4 people having a blood type of A? (Enter the decimal value)
