Question

A computer randomly picks a number from the group 105, 106, 107, 108, 109, 110, 111, 112, 113, 114. What is the probability the number selected is 111 or smaller than 107? Enter your answer in the box as a decimal.

Answer 1

I think 3/10 is the answer

Answer 2

Probability the number selected is 111 or smaller than 107 = 0.3

Explanation:

Probability is the ratio of number of favorable outcome to the total number of outcomes.

Total number of outcomes when picking a number from the group 105, 106, 107, 108, 109, 110, 111, 112, 113, 114 = 10

Number less than 107 in the group are 105 and 106

Number of favorable outcome for the number selected is 111 or smaller than 107 = 3

Probability the number selected is 111 or smaller than 107
`=(3)/(10) =0.3`
