Question 21) Out of N-6 TV, K-2 are defective and 4 are fine Let X be the number of TV that are defective in randomly selected n 2 TV X follows Hypergeometric distribution with parameters N- 6, K 2,n 2 Hypergeometric random variable can only take integer values in range [max (0, n-K-N), min (n. K)]-0.2 (e)( 2) P(X = k) T2 1×6 6 2 (2)15155 T2 Use excel function HYPGEOM.DIST k, n, K, N. cumulative) to calculate Px(0): HYPGEOM.DIST( 0, 2, 2, 6. FALSE) 0.4 P(X 0) =- 0.4000
