Question

If the school bus is on time 8% of the time and you are on time 7% of the time, what is the probability that both you and the bus will be on time

Answer 1

0.56%

Explanation:

Probability of A and B is P(AB)

Probability of A is P(A)

Probability of B is P(B)

When A and B are independent (unrelated)

P(AB)=P(A)P(B)

In this case

0.08(0.07)=0.0056 or 0.56%
