6. A stoplight at an intersection stays red for 60 second, changes to green for 45 seconds, and then turns yellow for 15 seconds. If Jamal arrives at the

intersection at a random time, what is the 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

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

i dont know sorry

step-by-step explanation:

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
