Predictions with Probability

A spinner with the numbers 1 - 5 was spun 20 times, and the results are shown in the table. Based on the table, predict the number of times the spinner will land on the number 5 if the spinner is spun 60 times.

• 1/2

• 1/3

• 1/5

• 1/8

Theoretically, what is the probability of landing on a number greater than 6 if the spinner is spun 200 times?

• 1/6

• 1/8

• 1/4

• 1/2
