Question

A spinner has 5 sections, numbered 1 through 5. The table below shows the results of 50 spins. Section Number of Times Spun 1 10 2 4 3 7 4 8 5 21On the next spin, which is the best estimate of the probability that the spinner lands on an odd number greater than 2? A. 0.40 B. 0.56 C. 0.72 D. 0.76

Answer 1

Based on the information of the table, you can conclude that the probability of geting an odd number greater than 2 was:

For section 3:

7/50 = 0.14

For section 5:

21/50 = 0.42

On the next spin, the probability of getting an odd number greate than 2 is given by the sum of the previous probabilites:

0.14 + 0.42 = 0.56

Hence, the probability is 0.56
