Question

Manny, Rachelle, and Peg race each other in carts. There are no other racers, and exactly one racer wins each race (no ties allowed!). The following graph shows an incomplete probability model for who will win any given race.
What is the probability that Rachelle will win any given race?
A. 0.1
B. 0.3
C. 0.4
D. 0.6

Answer 1

Answer:

0.4

Step-by-step explanation:

Since only one person wins the race, the sum of the probabilities is 1. Therefore, the probability that Rachelle wins the race is 1-0.35-0.25 = 0.4.
