Question

If P(A)=0.2,P(B)=p,P(A∪B)=0.6 and A and B are given to be independent events, find the value of p.​

Answer 1

Answer:

mark me barinliest

Step-by-step explanation:

P(A)=0.2

P(B)=p

P(AUB)=0.6

Since A and B are independent P(A∩B)=P(A)×P(B)=0.2p

P(AUB)=P(A)+P(B)-P(A∩B)

0.6=0.2+p-0.2p

p=0.5
