A Short Lesson on Probability By Mrs. Garcia
What are the Chances? A probability experiment is something that can happen in more than one way.
6 10 12 52 The outcomes of an experiment are the ways it can happen. The event is the particular outcome you are looking for.
P(H+T) = 2 = 1 __ __ 4 2 H H T T H T T H The Probability of an Event = P(Event) = the number of ways it can happen the number of possible outcomes ?
a) b) 3 5 1 4 2 5 1 2 1 5 1 4 A A A B B B Try these… P(red) P(blue) P(yellow or blue)
CARDS What is the probability of getting 4 fives? P(4 fives) = 4 13
DICE What is the probability of getting an even number? 2 13 P(even) =
COINS What is the probability of rolling two coins and getting H first and then T? P(H & then T) = 1 4
What is the probability that you will get an A this marking period?
