JEE Math Practice Question
For three events A, B and C, P(Exactly one of A or B occurs) = P(Exactly one of B or C occurs) = P (Exactly one of C or A occurs) = $${1 \over 4}$$ and P(All the three events occur simultaneously) = $${1 \over {16}}$$. Then the probability that at least one of the events occurs, is :
- A.$${7 \over {16}}$$
- B.$${7 \over {64}}$$
- C.$${3 \over {16}}$$
- D.$${7 \over {32}}$$
