Question

A group of people were asked if they had run a red light in the last year. 478 responded "yes", and 200 responded "no".Find the probability that if a person is chosen at random, they have run a red light in the last year.

Answer 1

`P=0.705`

Step-by-step explanation

The probability that if a person has run a red light in the last year can be found by dividing the number of people that have run a red light in the last year by the total number of people in the group.

The total number of people in the group is:

`\begin{gathered} 478+200 \\ \Rightarrow678 \end{gathered}`

Therefore, the probability is:

`\begin{gathered} P=(478)/(678) \\ P=0.705 \end{gathered}`
