Question

a spinner with 10 equally sized slices has3 Blue slices2 Yellow slices5 Red slicesthe dial is spun & stop at random what is the Probability that the dial Stops on a slice that is NOT blue? write the fraction in the simplest form

Answer 1

Solution

The number of possible outcomes is 10

We need to find the probability that it is blue

Probability is given as = number of required outcomes/ number of the possible outcome

The probability that the dial Stops on a slice that is blue = 3/10

The probability that the dial Stops on a slice that is NOT blue = 1 - Probability that the dial Stops on a slice that is blue = 1 - 3/10
