When we set two ratios (or fractions) equal to each other we called them what?
A Proportion
Person A and B play rock, paper, scissors. Person A could win, Person B could win, and they could tie. They play 50 times. Person A won 20 times, Person B won 20 times, and they tied 10 times. What's the theoretical probability they tie? (Fraction and Percent)
1/3 or 33%
Person A and B play rock, paper, scissors. Person A could win, Person B could win, and they could tie. They play 50 times. Person A won 20 times, Person B won 20 times, and they tied 10 times. Based on the data, how often do you expect each person to tie if they play 300 games?

You play a game in which a 6 sided number die is rolled. Is this a fair game? Explain
Yes because each outcome has the same chance of showing up.
Ivy makes 3 point shots 33% of the time (1/3). That means he misses 67% of the time (2/3). What's the probability that he makes two shots in a row? Then what's the probability he misses two shots in a row? (Fraction and Percent)
