We have,
P(A)=0.3,P(B)=0.6
So,P(¯¯¯¯A)=1−0.3=0.7
AndP(¯¯¯¯B)=1−0.6=0.4
Part (a)
P(A and not B)=P(A)×P(¯¯¯¯B)
P(A and not B)=0.3×0.4=0.12
Part (b)
P(neither A and nor B)=P(¯¯¯¯A)×P(¯¯¯¯B)
P(A neither A and nor B)=0.7×0.4=0.28
Given two independent events A and B such that P (A) = 0.3, P (B) = 0.6. Find
(i) P (A and B) (ii) P (A and not B)
(iii) P (A or B) (iv) P (neither A nor B)
