Weekend HW!

This weekend please complete the "Probability and Venn Diagrams" worksheet and the "A tire manufacturer..." worksheet provided in class (or below). 

The answers to each of these questions are posted below--be sure to check your answers to these!!!

On Monday in class we'll move on to calculating some probabilities "without replacement" and we'll explore the conditional probability formula! See you there!

You don't know how to do all of it yet, but if you'd like to get a head start you can do some of these--here's Monday night's homework:

a. 70th percentile of stopping distances = 128.41 ft

b. P(stopping distance between 110 and 140) = 0.979

c. P(stopping distance >130) = 0.2209
