Homework Help: statistics

Posted by Shelby on Monday, June 20, 2011 at 5:45pm.

Okay, I'm having trouble understanding the difference between "and" and "or" in problems.
For example:
-When drawing a single card, find the probability of getting a 4 OR a diamond.
-When drawing a single card, find the probability of getting a jack AND a black card.

What is the difference? What are the answers to these so I can check my study guide? Please help, I have a test soon!
