Probability = Favorable Outcomes / Total Outcomes
Favorable outcomes = Choosing a person who has not yet been called = 120 - 45 = 75
Total Outcomes = Choosing 1 out of 120 from the list = 120
The required probability = 75 / 120 = 5 / 8 = 0.625
Option D

The probability that the prospect has not yet received a call from salesperson A \(= \frac{120 - 45}{120} = \frac{75}{120}=\frac{5}{8}=0.625\)
