Question

A spinner is numbered from 1 through 10 with each number equally likely to occur. what is the probability of obtaining a number less than 4 or greater than 7 in a single spin?

Answer 1

Total possible outcome = 10

Number of outcome less than 4 or greater than 7 = 6
{1, 2, 3, 8, 9, 10}

P( less than 4 or greater than 7) = 6/10 = 3/5

Answer: 3/5
