Question

A number is randomly picked from this list: 10,25,30,40,50,55.What is the probability of picking an off number

Answer 1

1/3

Explanation:

An odd number is a number ending in 1, 3, 5, 7 or 9

In this list the odd numbers are: 25 and 55

There are 6 numbers in this list and 2 of these numbers are odd so the probability is 2/6 which can be simplified to 1/3
