Homework Solutions

Lesson 10.4 Probability Compound Events Students will use tree diagrams, tables, or a formula to find the number of possible outcomes. Students will find probabilities of compound events. (MP4 Model with Mathematics. CCSS.7.SP.8)

Compound Probability involves MORE than one event! Vocabulary: Compound Probability- refers to probability of more than ____________ event. Tree Diagram– shows the total possible __________________ of an event. Fundamental Counting Principle– used to determine the total possible ____________________ when more than one event is combined. Calculating Compound Probability– may use a tree diagram OR may _________________ the first event TIMES the second event. one outcomes outcomes MULTIPLY

Tree Diagrams: Tossing Two Coins: Total Outcomes: _____ 4 Coin 2 Heads Tails Tails Heads Total Outcomes: _____ 4

Tossing Three Coins: H T H T H T H T Total Outcomes: _____ 8 Coin 3 Heads _____ Tails H T H T Tails Heads _____ H T H T Total Outcomes: _____ 8
