Determine whether the given tables represent a discrete probability distribution. Write a check mark ( v ) on your answer sheet if the situation represents a discrete probability distribution. Otherwise, write a cross mark (X). Each item is worth 1 point. 1 . X 0 2 P(X = x ) 0.16 0.40 0.23 0.21 2. X 2 3 P(X = * ) 0 3. X 0 2 P(X = x ) 0.21 0.37 0.52 0.1 4. P(1) = 0.12; P(2) = 0.28; P(3) = 0.25; P(4) = 0. 17 ; P(5) = 0.19 5. P(1) = 1/12 ; P(2) = 1/4; P(3) = 1/6; P(4) = 1/2
