A sports bag contains 3 tennis balls, 4 baseballs, and 8 golf balls. Each is equally likely to be chosen. Which of the following models could be used to simulate this situation?

• flipping a coin fifteen times

• spinning a spinner with three equal sections

• choosing from 3 red marbles, 4 yellow marbles, and 8 blue marbles

• rolling a number cube labeled one through six fifteen times

A store is handing out coupons worth 10%, 15%, 20%, or 25% off. Each coupon is equally likely to be handed out. Which of the following models could be used to simulate this situation?

• flipping a coin four times

• spinning a spinner with four equal sections

• rolling a number cube labeled one through six one time

• rolling a number cube labeled one through six four times

What are the different possible outcomes for the spinner above?

• 1, 1, 2, 2, 2, 3, 3, 3

• 1, 2, 3

• 8

Which spinner has equally likely outcomes?

True or False: If you spin this spinner once, landing on one and landing on 2 have the same probability. 

• True:  There are 3 spaces for you to land on each of those numbers 
• False:  The space of 2 on the spinner is greater than the space for 1.
