While driving from his home to his workplace, chris has to pass through two traffic lights. the general probability of getting a red signal at the first traffic light (event a) is 36%. the general probability of getting a red signal at the second traffic light (event b) is 25%. the probability of chris getting a red signal at both traffic lights is 9%.

A and B are independent events

Step-by-step explanation:

Because P(a) is .36 or 36% and P(b) is .25 or 25% and at both A and B there is still a .9 chance, so no matter what the first stop light does it wont change the probability of the second light being whatever it is. It makes a and b INDEPENDENT.
