Question

p (A)=0.15 p (AUB)=0.45 findp (B)

Answer 1

When it is given that A and B are independent it implies that P(AՈB)=0.

So,using the formula P(A U B)=P(A)+P(B)+P(AՈB), we get P(B)=P(A U B)-P(A) which gives P(B)= 0.45 - 0.15 = 0.3

So. your answer will be 0.3.

Hope this helps and Good Luck.
