The probability that an event will not happen is Upper P(E')=0.56 Find the probability that the event will happen.

The probability that an event will happen is the complement of the probability that it will not happen.

Given:
- \( P(E') = 0.56 \), where \( E' \) is the complement of the event \( E \) (i.e., the event not happening).

To find \( P(E) \), the probability that the event will happen, use the formula:

\[
P(E) = 1 - P(E')
\]

Substitute the given value:

\[
P(E) = 1 - 0.56 = 0.44
\]

So, the probability that the event will happen is \( P(E) = 0.44 \).
