1. The probability of finding five people with 20-20 vision is 1.27 * 10⁻⁸

### What is probability?

Probability is the ratio of expected outcomes to possible outcomes.
The the probability of finding five people with 20-20 vision is obtained as follows:
Probability that an individual has 20-20 vision = 0.17
The probability that an  individual does not have 20-20 vision = 1 – 0.17 = 0.83
Number of students in the class = 55
The probability of finding five people with 20-20 vision = 0.17⁵ * 0.83⁵⁰
The probability of finding five people with 20-20 vision = 1.27 * 10⁻⁸
In conclusion, probability is the measure of the of the likelihood of an event happening or not.
