The probability that the event occurs is0.5.

Step by step solution

01

Step 1. Given information.

The given statement is:

An experiment has 20 possible outcomes, all equally likely. An event can occur in five ways. The probability that the event occurs is .

02

Step 2. Explanation.

The probability of an event can be determined using the following formula:

P=fN,

where N is the total number of outcomes and f is the number of positive outcomes.

Therefore, f=5andN=20.

The probability of the event is:

=520=0.5

The probability that the event occurs is 0.5.
