A group of people were asked if they had run a red light in the last year. 148 responded "yes", and 358 responded "no".
Find the probability that if a person is chosen at random, they have run a red light in the last year.
148/506 = about 3/10
29.25
29.25 = about 3/10
To find the probability that if a person is chosen at random, they have run a red light in the last year, we need to divide the number of people who responded "yes" by the total number of people surveyed.
In this case, we are given that 148 people responded "yes", and the total number of people surveyed is 148 + 358 = 506.
So, the probability is calculated as:
Probability = Number of "yes" responses / Total number of responses
= 148 / 506
Now, to calculate this probability:
Probability = 0.2927
Therefore, if a person is chosen at random, there is approximately a 0.2927 (or 29.27%) probability that they have run a red light in the last year.
