If `A` and `B` are mutually exclusive events such that `P(A)=0.20` and `P(B)=0.30` , find `P(AuuB)`

Explanation

To solve the problem, we need to find \( P(A \cup B) \) given that events \( A \) and \( B \) are mutually exclusive.

### Step-by-Step Solution:

1. **Understand the Definition of Mutually Exclusive Events**:
- Events \( A \) and \( B \) are mutually exclusive if they cannot occur at the same time. This means that the intersection of \( A \) and \( B \) is empty.
- Mathematically, this is represented as \( P(A \cap B) = 0 \).
