Using it's concept, it is found that there is a 0.624 probability that the employee is not late for work.
<h3>What is a probability?</h3>A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
Researching in the internet, it is found that the probability that the employee is stopped at any of the traffic lights is as follows:
- Traffic light A: 0.8.
- Traffic light B: 0.1.
- Traffic light C: 0.4.
He will be late if he is <u>stopped at more than 1 traffic light</u>, as he plans to arrive 2 minutes early and each stop takes 2 minutes.
Hence, the probability that he is stopped in at most one light is given by:
0.624 probability that the employee is not late for work.
