Suppose that the time students wait for a bus can be described by a uniform random variable X, where X is between 0 minutes and 60 minutes.

a. What is the probability that a student will wait between 0 and 30 minutes for the next bus?

b. What is the probability that a student will have to wait at least 30 minutes for the next bus?

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

x = 12

y = 1

for the points!
