A die is thrown. Let A be the event that the number obtained is greater than 3. Let B be the event that the number obtained is less than 5. Then `P""(AuuB)` is (1) `3/5` (2) 0 (3) 1 (4) `2/5`

Explanation

To solve the problem, we need to find the probability of the union of two events A and B when a die is thrown.

### Step-by-Step Solution:

1. **Define the Sample Space**:
The sample space S when a die is thrown consists of the outcomes {1, 2, 3, 4, 5, 6}.

2. **Define Event A**:
