Using it's concept, it is found that the probability of rolling an even number or flipping a tail is of .
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 12 outcomes. Of those, 3 result in an even number and a tail, 3 more in an even number but not tail and 3 in a tail but an odd number, hence there are 9 desired outcomes.
Hence, the probability is given by:

Answer:
0.75 = 75% probability that he will have to wait at a red light for more than 15 seconds
Step-by-step explanation:
At each second, the stoplight is equally likely to change, which means that we use the uniform probability distribution to solve this question.
Uniform probability distribution:
Has two bounds, a and b. The probability of finding a value higher than x is given by:
Red for 60 seconds
So when Jamal arrives it can change in any number of seconds between 0 and 60, that is,
Probability that he will have to wait at a red light for more than 15 seconds?
0.75 = 75% probability that he will have to wait at a red light for more than 15 seconds
