The probability for success of an event is P(A), and the probability of success of a second, independent event is P(B). What is the probability of both events occurring, in that order? P(A) • P(B)
P(A + B)
P(A x B)
P(A) + P(B)

Given:

The probability for success of an event is P(A)

The probability of success of a second, independent event is P(B).

To find:

The probability of both events occurring, in that order.

Solution:

If A and B are two independent events, then

It is given that,

The probability for success of an event is P(A)

The probability of success of a second, independent event is P(B).

Since A and B both are independent event and we need to find the probability of both events occurring, in that order, i.e., , therefore .

Hence, the correct option is A.

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
