Answer
Option A is correct.
Probability of a value in the sample space being anywhere from 0 to 20 = 80%
Step-by-step explanation
The probability of an event is calculated as the number of elements in the event divided by the total number of elements in the sample space.
For this question,
Number of boxes from 0 to 20 = 20
Total number of boxes in the density graph = 25
Probability of a value in the sample space being anywhere from 0 to 20 = (20/25) = 0.8 = 80%
Hope this Helps!!!
