CCSS Description: Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation. a. Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs. b. Represent sample spaces for compound events using methods such as organized lists, tables and tree diagrams. For an event described in everyday language (e.g., “rolling double sixes”), identify the outcomes in the sample space which compose the event. c. Design and use a simulation to generate frequencies for compound events. For example, use random digits as a simulation tool to approximate the answer to the question: If 40% of donors have type A blood, what is the probability that it will take at least 4 donors to find one with type A blood?
This worksheet gives learners the opportunity to practice writing probability as fractions confidently with the familiar theme of rolling a dice. Students will write the probability of single outcomes occurring as well as combined outcomes such as rolling a one or a two. Learners will need to be familiar with multiples, factors, primes, square numbers, and triangle numbers, as many questions include this language. Also included is a section where students will mark the probability of six outcomes occurring on a scale from 0 to 1. Encourage your students to simplify all their answers.
