If A and B are independent events with $P(A)=0.8$ and $P(B)=0.4 $, then value of $P(A ∪ B)$ is : |
0.58 0.66 0.88 0.98 |
0.88 |
The correct answer is Option (3) → 0.88 $P(A)=0.8,P(B)=0.4$ Since, A and B are independent events, $P(A∩B)=P(A)×P(B)$ $=0.8×0.4=0.32$ $P(A∪B)=P(A)+P(B)-P(A∩B)$ $=0.8+0.4-0.32=0.88$ |
