INDEPENDENT EVENTS

Events that do NOT have an affect on another event. Examples: Tossing a coin Drawing a card from a deck

P(A, then B) = P(A) X P(B)

Example You draw from a hat slips of paper numbered 0 – 9. After drawing a slip of paper, you look at the number then replace it in the hat. Find the probability of: 1. Drawing 2 sevens 2. Drawing an odd number, then an even. 3. Drawing a 3, then an even number.
