At this rate, how many minutes will it take her to run 9 laps? 3. The ratio of tomato plants to green bean plants in a garden is 7 to 3. If there are 42 tomato plants in the garden, how many green bean plants will there be?**WarM Up**Stephanie and Tamara both started running a race at 8:15 A.M. Stephanie finished the race in 4hours 30minutes. Tamara finished the race in 1hour 15minutes after Stephanie did. At what time did Tamara finish the race? A bus arrived at its destination at 2:15 P.M. If the trip took 3 hours and 50 minutes, at what time did the bus depart?**Find and interpret the probability of a simple event.**• outcomes • simple event • probability • random • complementary events**Answer:**Find Probability There are six equally likely outcomes on the spinner shown. Find the probability of landing on 1. There is one section of the spinner labeled 1.**A.**B. C. D. A number cube is rolled. Find the probability of rolling a 4. • A • B • C • D**Answer:**Find Probability There are six equally likely outcomes on the spinner shown. Find the probability of landing on 2 or 4. The word or indicates that the number of favorable outcomes needs to include the section labeled 2 and the section labeled 4. There is one section of the spinner labeled 2 and one section labeled 4.**A.**B. C. D. A number cube is rolled. Find the probability of rolling a number greater than 3.**At a school carnival, Sarosha’s little sister wants to**play the Duck Pond game. Each player wears a blindfold and chooses a duck from a tub of water. The player then wins the prize written on the bottom of the duck. There are 3 ducks with doll, 3 ducks with jump rope, 4 ducks with coloring book, and 6 ducks with bubble gum. What is the probability that Sarosha’s sister will choose a duck printed with bubble gum?**Find Probability of the Complement**There are six equally likely outcomes on the spinner shown. The spinner is spun once. Find the probability of not landing on 6. The probability of not landing on 6 and the probability of landing on 6 are complementary. So, the sum of the probabilities is 1.**Answer:**Find Probability of the Complement**A store is having a Wheel of Savings sale. They allow each**customer to spin their wheel to earn a discount off of their purchase. What is the probability of getting 15% off? 10 % 15 % 15 % 50 % 10 % 10 % 15 % 20 % 15 % 20 %**A.**B. C. D. A number cube is rolled. Find the probability of not rolling an even number. • A • B • C • D**Lesson 4 Ex4**Find Probability of the Complement SPORTSA sportscaster predicted that the Tigers had a 75% chance of winning tonight. Describe the complement of this event and find its probability. The complement of winning is not winning. The sum of the probabilities is 100%. Answer: So, the probability that the Tigers will not win tonight is 25%.**SLEEPOVERCelia guesses the probability that her parents will**allow her to sleep over at her best friend’s house tonight is 55%. What is the probability that Celia will not be allowed to sleep over? • A • B • C • D A. 20% B. 25% C. 45% D. 50%**If you spin the spinner shown below, what is the probability**of landing on pink?
