Question

Trent has a box of balloons for the school holiday party. There are 60 balloons in the box. Twenty-five of the balloons are red, fifteen of the balloons are blue and twenty of the balloons are yellow. What is the probability that a randomly selected balloon will be red? Determine the likelihood of this event.

Answer 1

Given data:

The total numbers of balloons are n=60.

The numbers of red balloons are r=25.

The numbers of blue balloons are b=15.

The numbers of yellow balloons are y=20.

The expression for the probability that a randomly selected balloon will be red.

`\begin{gathered} P(r)=(r)/(n) \\ =(25)/(60) \\ =(5)/(12) \end{gathered}`

Thus, there is 5/12 probability that a randomly selected balloon will be red.
