Answer 1

Answer:

(a) 0.5

(b) 0.3

Step-by-step explanation:

P(A) = 0.5

P(B) = 0.4

P(A∩B) = 0.3

Find the probability that A does not occur:

P(not A) = 1 - 0.5 = 0.5

Find the probability that neither A nor B occurs:

P(not A) = 0.5

P(not B) = 1 - 0.4 = 0.6

P(Not A nor B) = 0.5 x 0.6 = 0.3

Answer 2

Answer:

(a) =0.5

(b)=0.3
