Question

In a video game, Gate 3 is open 40% of the time and Gate 4 is open 20% of the time. The chance of both gates being open at the same time is 15%. Draw a tree and Venn diagram (with probabilities labeled) to model the scenario. What is the P(Gate 3 and Gate 4 are both open)?

A.60%
B.15%
C.100%
D.0%

Answer 1

The answer to "What is the P(Gate 3 and Gate 4 are both open)?" is

B: 15%

It is because they state that the chance of both gates being open at the same time is 15% and that chance is indeed the probability.
