We want to see who has the luck! Tally up the number of times each player wins. Play from games. PlayersTallyGames Won Player 1 Player 2 Player 3 Player 4 Player 5

Answer These Questions Which player won the most games? Why do you think this player won? What is the probability of Player 1 winning the game? What is the probability of Player 2 winning the game? What is the probability of Player 3 winning the game? What is the probability of Player 4 winning the game? What is the probability of Player 5 winning the game? If you had to choose, which player would you want to be?

Date: 03/23/11 By: Mr. Menjivar Today’s Title Experimental Probability

Standard SDAP 3.2: Use data to estimate the probability of future events.

Objective To find experimental probability To use simulations

Vocabulary (Shout Outs) Outcome → result of an action Event → possible outcomes Complement → opposite of the event

What is experimental probability? Probability involves predicting future events based on the following… Experimental Probability

Example You attempt 16 free throws in a basketball game. Your results are shown. What is the experimental probability of making a free throw

Finding Experimental Probability 0 = MISS 1 = MAKE

Example A bicycle company checks a random sample of bikes. The table shows the results. Predict the number of defective bikes in a batch 1,300. Defective Bikes Checked 12400

Example Find the experimental probability that 2 of 3 children in a family are girls. Assume that girls and boys are equally likely. Simulate the problem by tossing three coins. Let heads represent a girl. Let tails represent a boy.
