Warm-Up Question
They all give him the SAME chance of going to bed at 11:00! Eleven o’clock covers ½ of each circle.Slide3
11:00 and 9:00 are equally likely to occur
Kalvin’s father is probably not likely to agree because he is more likely to go to bed later than 9:00.1. Which time do you think is most likely to occur?
2. Is Kalvin’s father likely to agree to use this spinner? Explain why or why not.Slide4
B. 1. Find the experimental probability that the pointer lands
on 9, on 10, and on 11. 2. After how many spins did you decide to stop spinning? Explain why. 3. Suppose Kalvin spins the pointer 64 times. Based on your experiment, how many times can he expect to land on 9, 10, and 11? Slide5
1. Find
the theoretical probability that the pointer lands on 9, on 10, and on 11.
Do your
experimental probabilities
match the
theoretical
probabilities
?
Explain
what you notice
.
Suppose Kalvin spins the pointer 64 times. Based on your theoretical probabilities, how many times can he expect to land on 9, 10, and 11?
Describe one way Kalvin’s father can design a spinner so that Kalvin is most likely to go to be at 9.

D. The cooks at Kyla’s school make the spinners below to help them choose the lunch menu.
They let the students take turns spinning. For parts (a)-(c), decide which spinner you would choose. Explain your reasoning.a. Your favorite lunch is pizza. b. Your favorite lunch is lasagna. c. Your favorite lunch is hot dogs.
P (pizza) =
P (lasagna) =
P (hot dog) =

Find the theoretical probability of landing on A, B, C, D, E.Hint: What must you do first?Divide into equal size pieces!What is your common denominator?P(A) = 4/16 = 1/4P(B) = 2/16 = 1/8P(C) = 2/16 = 1/8P(D) = 1/16P(E) = 7/16
