Question

A spinner has 7 identical sections. Two sections are blue, 1 is red, and 4 of the sections are green. Suppose the probability of an event happening is 2/7 . What does each number in the ratio represent? What outcome matches this probability?

Answer 1

The numerator represents the chance of landing on the colour, and the denominator represents the number of spots you could land on. You have a 2 out of 7 chance to land on blue because there are 2 blue spots. This means that for every 2 times out of 7 spins you would land on blue.
