Question

if A and B are independent events such that P(A)=0.3 and(PB)=0.6,find P (not A and not B )
​

Answer 1

Answer:

Finding P (A and not B):

If A and B are independent events, A¯A¯ and B¯B¯ are also independent.

⇒P(A∩B¯)=P(A)×P(B¯)=P(A)×(1−P(B))=0.3×(1−0.6)=0.3×0.4=0.12⇒P(A∩B¯)=P(A)×P(B¯)=P(A)×(1−P(B))=0.3×(1−0.6)=0.3×0.4=0.12
