Question

Which of the following choices is the correct probability for this scenario?

a) 0.161

b) 0.446

c) 0.762

d) 0.146

Answer 1

To find the probability of waiting more than seven minutes given a person has waited more than four minutes, use conditional probability.

Step-by-step explanation:

To find the probability of waiting more than seven minutes given a person has waited more than four minutes, we need to use conditional probability.

Let A be the event of waiting more than four minutes, and B be the event of waiting more than seven minutes.

P(B|A) = √ P(A) = √ 0.25 = 0.5

Therefore, the correct probability is 0.5 (c).
