Question

A randomly generated list of integers from 1 to 5 is being used to simulate anevent, with the numbers 1, 2, 3, and 4 representing a success. What is theestimated probability of a success?

Answer 1

The theoretical probability is defined as the ratio of the number of favourable outcomes to the number of possible outcomes.

The randomly generated list has the numbers from 1 to 5, therefore, the total amount of elements is 5, which is the number of possible outcomes.

Our event consists of choosing from this list any of the numbers from 1 to 4, which is a total of 4 elements, which represents the number of favourable outcomes.4

Their ratio is:

`(4)/(5)`

Rewritting this ratio as a percentage, we have:

`(4)/(5)=(80)/(100)=80\%`

The answer is option B.
