Jones figures that the total number of thousands of miles that a used auto can be driven before it would need to be junked is an exponential random variable with parameter
Smith has a used car that he claims has been driven only 10,000 miles.
If Jones purchases the car, what is the probability that she would get at least 20,000 additional miles out of it?
Repeat under the assumption that the lifetime mileage of the car is not exponentially distributed but rather is (in thousands of miles) uniformly distributed over (0, 40).
The two-way table summarizes data on the gender and eye color of students in a college statistics class. Imagine choosing a student from the class at random. Define event
A: student is male and event
B: student has blue eyes.
Copy and complete the two-way table so that events A and B are independent.
In this problem, you will prove the sin and cos sum formulas in two ways.
Use Euler’s formula:
Use the rotation matrix
