Question

A game of chance consists of spinning an arrow, which comes to rest pointing at one of the numbers 1,2,3,4,5,6,7,8 and these are equally likely outcomes. Find the probability that the arrow will point at any factor of 8.

Answer 1

Correct Answer - ` 3/8`
All possible outcomes are 1,2,3,4,5,6,7,8.
Number of all possible outcomes is 8.
All factors of 8 are 2,4,8.
Number of favourable outcomes = 3.
Probability that the arrow will point at any factor of 8 = ` 3/8`.
