Question

The spinner is divided into 10 equal sections. A spinner divided into 10 equal sections labeled 1 through 10. Which event has theoretical probability of exactly One-fifth? Select three options. spinning a number less than 3 spinning a 4 or 5 spinning an odd number spinning a number greater than 8 spinning a number less than 8

Answer 1

Answer:

spinning a number less than 3

spinning a 4 or 5

spinning a number greater than 8

Step-by-step explanation:

spinning a number less than 3

P(1 or 2) = number of 1 or 2's / total = 2/10 = 1/5   true

spinning a 4 or 5 spinning

P(4 or 5) = number of 4 or 5's / total = 2/10 = 1/5   true

an odd number

P(odd number) = number of 1,3,5,7,9 s / total = 5/10 = 1/2   false

spinning a number greater than 8

P(9 or 10) = number of 9 or 10's / total = 2/10 = 1/5   true

spinning a number less than 8

P(less than 8) = number of 1,2,3,4,5,6,7's / total = 7/10 = false

Answer 2

Answer:

the answer is "4 or 5","less than 3", and "a number greater than 8"

Step-by-step explanation: the only 0ne than is not possible is "a number less than 8" because the probibility is an 80% chance, not a 20% chance.
