Suppose p(e) = 57⁄100 , p(fc ) = 7⁄20 , and p(f ∩ ec ) = 31⁄100. find p(e ∪ f).

Probabilities are used to determine the chances of an event.

The value of P(e u f) is 22/25.

The given parameters are:

First, we calculate P(f).

Using the complement rule, we have:

Also, we have:

This gives:

So, we have:

So, we have:

This gives

Take LCM

Simplify

Hence, the value of P(e u f) is 22/25.
