`A\ a n d\ B` are two events such that `P(A)=0. 54 ,\ P(B)=0. 69\ a n d\ P(AnnB)=0. 3.\ ` Find : `P( A nn B )`

Explanation

To solve the problem, we need to find \( P(A' \cap B') \), which is the probability of the complement of events A and B occurring together. This can be calculated using the following steps:

### Step 1: Understand the relationship between events
We know that:
\[ P(A' \cap B') = P((A \cup B)') = 1 - P(A \cup B) \]
This means that the probability of neither A nor B occurring is equal to one minus the probability of either A or B occurring.
