P(B|A) = P(B)

Step-by-step explanation:

For dependent events the outcome of first event affects the outcome of the second event.

If B is a dependent event on A, then the conditional probability of B is given by P(B|A).

P(B|A) = P(B)

Hence, the correct option is (c).

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
