The probability of the event that the number picked is less than or equal to 16 is 33.33%. Then the probability of the complement of event A is 66.67%.
<h3>What is probability?</h3>Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
A number is randomly selected from {15, 16, 17, 18, 19, 20}.
A is represented by the event that the number picked is less than or equal to 16.
Total event = 6 {15, 16, 17, 18, 19, 20}
Favorable event = 2 {15, 16}
Then the probability of the event that the number picked is less than or equal to 16 will be
The probability of the complement of event A will be
The probability of the complement of event A is 66.67%.
