12.1 Find Probability and Odds Mrs. vazquez Geometry

S.id.5, s.cp.1 Essential Question: How are different odds and probabilities calculated? Objective: Students will be able to find sample spaces and probabilities.

theoretical probability P(A) = # of favorable outcomes total outcomes Ex: You toss a coin & roll a number cube. What is the probability that the coin shows tails & the number cube shows 4?

experimental probability *based on repeated trials of an experiment P(A) = # of successes # of trials Ex:

odds Odds in favor: # of favorable outcomes # of unfavorable outcomes Odds against: # unfavorable outcomes # favorable outcomes
