Define probability.
The probability of an event occurring is known as probability. This might range from an occurrence being impossible to have a chance to happen to be certain for sure. Probability is measured mathematically on a scale from 0 to 1.
Given,
The person selected who drives a truck exercises four or more times per week.
P(The person selected drives a truck and exercises four or more times per week)
= 36/120 + 52/120 - 12/120
= 76/120
Simplifying,
= 19/30
= 0.633(approximately)
The probability that the person selected drives a truck exercises four or more times per week is 0.633.
