Unit 8: Statistics and Probability Objective: Students will express the probability of an event as a decimal, fraction, percent and ratio.

Objective: Students will identify the probability of an event as a decimal, fraction, percent and ratio. Vocabulary: Tossing a coin is an example of an experiment. Outcome: possible result of an experiment (such as heads) Event: Collection of outcomes

Objective: Students will identify the probability of an event as a decimal, fraction, percent and ratio. Probability: The probability of an event is the measure of the likelihood that the event will occur.

Objective: Students will identify the probability of an event as a decimal, fraction, percent and ratio. Finding a probability You randomly choose a day of the week for sending an to your cousin. Find the probability that you choose Tuesday. Solution: There is one favorable outcome which is Tuesday. The 7 possible outcomes are “Sunday,” “Monday,” “Tuesday,” “Wednesday,” “Thursday,” “Friday,” and “Saturday.” Probability of choosing Tuesday:

Objective: Students will identify the probability of an event as a decimal, fraction, percent and ratio. You roll a number cube. Find and describe the probability of the event: 1.) you roll an even number 2.) you roll a number less than 4 3.) you roll a 3 4.) you roll a number greater than 3

Objective: Students will identify the probability of an event as a decimal, fraction, percent and ratio. Expressing your results Once you get your results as a fraction you can express them as a decimal or as a percent. Lets practice: 1.) The probability of an event is Change this to a decimal and then to a percent.

Objective: Students will identify the probability of an event as a decimal, fraction, percent and ratio. Lindsey is practicing her basketball shooting. She took 25 practice shots and her results are listed below. Made Missed Missed Made Made Missed Made Made Missd Missed Missed Made Made Made Made Made Missed Made Missed Made Made Made Missed Made Missed Based on the results, what is the experimental probability she will make the next shot?

Objective: Students will identify the probability of an event as a decimal, fraction, percent and ratio. Jessica rolled a number cube 30 times and her results are shown below Based on her results, what is the experimental probability that Jessica will roll an even number on her next roll? A.) 0.12 B.) 0.18 C.) 0.40 D.) 0.60

Objective: Students will identify the probability of an event as a decimal, fraction, percent and ratio. A desk drawer contains 6 black pens, 5 blue pens, 4 red pens, and 5 green pens. Alex picks one pen from the drawer without looking. What is the probability Alex picks a blue pen? (express as a decimal)
