Question

While driving to work, Araceli passes through 3 stoplights. The probability distribution of the number of lights she stops at is shown below. What is the probability that Araceli has to stop at fewer than two lights for her ride to work?

A. 0.2
B. 0.4
C. 0.6
D. 0.8

Answer 1

The probability that Araceli has to stop at fewer than two lights for her ride to work is 0.7.

Step-by-step explanation:

To find the probability that Araceli has to stop at fewer than two lights for her ride to work, we need to sum the probabilities of stopping at 0 lights and 1 light.

Looking at the probability distribution, we see that the probability of stopping at 0 lights is 0.4 and the probability of stopping at 1 light is 0.3.

Adding these probabilities gives us a total probability of 0.7. Therefore, the probability that Araceli has to stop at fewer than two lights for her ride to work is 0.7.
