Warm-up Estimate the value of 177 to the nearest integer. Explain your reasoning.

Lesson 14: determining the theoretical probability of an event A simple event is an event having only one outcome at a time. Examples? The theoretical probability of an outcome is the ratio of favorable outcomes to all possible outcomes *all outcomes are equally likely

outcomes for each event. A number cube labeled 1 – 6 is rolled. List the outcomes for each event. Rolling an even number Rolling a multiple of 3 Rolling a prime number

There are 4 green marbles, 3 blue marbles, and 3 red marbles in a bag There are 4 green marbles, 3 blue marbles, and 3 red marbles in a bag. Give each answer as a decimal and as a percent. What is the probability of randomly choosing a green or red marble? What is the probability of randomly choosing a marble that is not blue?

A bucket has 10 balls numbered 1, 1, 2, 3, 4, 4, 4, 5, 6, and 6 A bucket has 10 balls numbered 1, 1, 2, 3, 4, 4, 4, 5, 6, and 6. If one ball is drawn at random, is there a greater chance of getting an even number or a multiple of 5? Explain.
