## Homework Statement

A question out of my a workbook I have:

We have sales from a shoe store:

Probability of Red Shoes 0.35

Probability of Green Shoes 0.40

Probability of Red, Green, Blue Shoes 0.05

Probability of Red and Green Shoes 0.1

Probability of Green and Blue Shoes 0.2

Probability of Red and Blue Shoes 0.25

Probability of Red or Blue Shoes 0.6

Probability of purchasing Blue shoes?

Probability of Red or Green?

Probability of Red or Blue?

Probability of Blue or Green?

Probability of not buying anything?

I'm not sure how to do probabilities in this format really?

Any suggestions?
