For the three events `A`, `B` and `C`, `P`(exactly one of the events A or B occurs) `= P`(exactly one of the events B or C occurs) `=P`(exactly one of the events C or A occurs)`= p` and `P`(all the three events occur simultaneously) `= p^2`, where `0ltplt1/2`. Then, find the probability of occurrence of at least one of the events `A`, `B` and `C`.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Define the probabilities for events A, B, and C
Let:
- \( P(A) = a \)
- \( P(B) = b \)
- \( P(C) = c \)
