In a bingo game, balls numbered 1-75 are placed in a bin. Balls are randomly drawn and not repalced. Find each probability for the first 5 balls drawn.
11. P(selection 5 two digit numbers): (22/25)(21/24)(20/23)(19/22)(18/21)=.495 (but this is not what's in the back of the book?)
13. P(5 even numbers or 5 numbers less than 30)...I don't think I'm using the proper logic in finding the probability of even numbers or numbers less than 30. I'm going to omit my work for that reason..
