Textbook Question

Chapter 5, Problem 5.13P

You arrive at a bus stop at 10A.M., knowing that the bus will arrive at some time uniformly distributed between 10 and 10:30.

a. What is the probability that you will have to wait longer than 10 minutes?

b. If, at 10:15, the bus has not yet arrived, what is the probability that you will have to wait at least an additional 10 minutes?

Definition Definition Probability of occurrence of a continuous random variable within a specified range. When the value of a random variable, Y, is evaluated at a point Y=y, then the probability distribution function gives the probability that Y will take a value less than or equal to y. The probability distribution function formula for random Variable Y following the normal distribution is: F(y) = P (Y ≤ y) The value of probability distribution function for random variable lies between 0 and 1.
