Question

The sections on a spinner are numbered from 1 through 8. If the probability of landing on a given section is the same for all the sections, what is the probability of spinning a number less than 3 or greater than 5 in a single spin?

Answer 1

5/8

Explanation:

There are two numbers from one to eight that are less than three (1 and 2). So 2/8 of the numbered sections are less than three.

There are three numbers from one to eight that are greater than five (6, 7, and 8). So 3/8 of the numbered sections are greater than five

Probability of getting a number less than three: 2/8

Probability of getting a number greater than five: 3/8

Probability of getting either in a single spin = 2/8 + 3/8 = 5/8
