Definition

Probability refers to how likely an event will occur. It means the chance of something to happen.
Random event pertains to something that is unpredictable.
Since a random event is unpredictable, you cannot give an exact calculation for something to occur.
The result of a random experiment is called an outcome.
The set of all the possible outcomes of a random experiment is called Sample Space, and it is denoted by ‘S’.
A subset of the sample space is called an Event.

Summary

Based on a survey result, 56% of the carnival goers tend to buy at least 2 cups of ice cream whenever they visit a Carnival park. What is the probability that all of the five random visitors in the carnival bought 2 cups of ice cream?

Solution:

Change 56% to decimal. Then multiply the value five times.

P(E) = (0.56)(0.56)(0.56)(0.56)(0.56)

P(E) = 0.550 or 5.50%

Therefore, the probability that all five Carnival visitors will buy 2 cups of ice cream is 0.550 or 5.50%
