Question

A group of people were asked if they had run a red light in the last year. 316 responded "yes", and 235 responded "no".Find the probability that if a person is chosen at random, they have run a red light in the last year._________Give your answer as a fraction or decimal rounded to 2 decimal places

Answer 1

Given:

Number of people had run a red light in the leap year = 316

Number of people had not run a red light in the leap year = 235

Required: Probability that a randomly chosen person had run a red light in the last year.

Step-by-step explanation:

Total number of people in the group were asked = 316+235 = 551

Probability that a randomly chosen person had run a red light in the last year

= Number of people had run a red light in the leap year/ Total number of people in the group were asked

`\begin{gathered} =(316)/(551) \\ =0.57 \end{gathered}`

Final Answer: Probability that a randomly chosen person had run a red light in the last year is 0.57.
