10. Example 4 MOVIES In a survey, 50 people were asked to pick which movie they would see this weekend. Twenty chose Brad’s Story, 15 chose The Ink Well, 10 chose The Monkey House, and 5 chose Little Rabbit. What is the experimental probability of someone wanting to see The Monkey House? There were 50 people surveyed and 10 chose The Monkey House. Predict Future Events Answer:

11. 1.A 2.B 3.C 4.D Example 4 SPORTS In a survey, 100 people were asked to pick which sport they would watch on TV over the weekend. Thirty-five chose football, 20 chose basketball, 25 chose hockey, and 20 chose soccer. What is the experimental probability of someone wanting to watch football? A.B. C.D.

12. Example 5 Predict Future Events MOVIES In a survey, 50 people were asked to pick which movie they would see this weekend. Twenty chose Brad’s Story, 15 chose The Ink Well, 10 chose The Monkey House, and 5 chose Little Rabbit. Suppose 300 people are expected to attend a movie theater this weekend to see one of the four movies. How many can be expected to see The Monkey House? 1 ● 300 = 5 ● xFind the cross products. Write a proportion. 300= 5xMultiply.

13. Example 5 Predict Future Events Answer: About 60 people can be expected to see The Monkey House. 60= xDivide each side by 5.
