Compound Events Compound event - an event that is a combination of two or more stages P(A and B) - P(A) X P(B)

 Probability- the likelihood that an event will have a particular result; the ratio of the number of desired outcomes to the total possible outcomes.

An outcome is a possible result An event is a specific outcome Random means all outcomes are equally likely to occur or happen. random = fair A favorable.

Lesson 10-6 Theoretical Probability Obj: The student will be able to 1) Determine the theoretical probability of an event 2) Convert between probabilities and odds HWK: Vocab: 1) equally likely 2) theoretical probability 3) fair 4) complement 5) odds COS: S-CP1

Find each theoretical probability Find each theoretical probability. Express as a fraction, decimal and percent. Ex 1) Rolling a 3 on a standard Ex 2) Rolling a number greater number cube than 3 on a standard number cube

Ex 3) Rolling an even number Ex 4) Rolling a multiple of 3 on on a standard number a standard number cube cube

Ex 5) A jar has green, blue, purple and white marbles Ex 5) A jar has green, blue, purple and white marbles. The probability of choosing a green marble is 0.2, the probability of choosing blue is 0.3 and the probability of choosing purple is 0.1. What is the probability of choosing white?

Ex 6) The probability of choosing a red card from a standard deck of playing cards is 50%. What are the odds of choosing a red card?

Ex 7) The odds against choosing a green marble from a bag are 5:3 Ex 7) The odds against choosing a green marble from a bag are 5:3. What is the probability of choosing a green marble?
