Question

Given that P(A)=0.4, P(B)=0.5, P(AՍB)=0.75. Find P(AꓵB)​

Answer 1

Explanation:

P(AՍB)=P(A)+P(B)-P(AꓵB)

0.75=0.4+0.5-P(AꓵB)

P(AꓵB)=0.9-0.75=0.15

Answer 2

Answer:

given,

P(A) = 0.4

P(B) = 0.5

P(AՍB) = 0.75

so, P(AꓵB) = P(AUB) - P(A) - P(B)

= 0.75 - 0.5 - 0.4

= 0.75 - 0.9

= -0.15
