Answer 1

The Solution:

Given:

A spinner is numbered 1 to 8.

Required:

Find the probability that the first number is 3 and the second number is 5 when the spinner is used twice.

The possible outcomes = 8

$P(3)=\frac{1}{8}$$P(5)=\frac{1}{8}$$P(a\text{ 3 and a }5)=\frac{1}{8}\times\frac{1}{8}=\frac{1}{64}$
