Question D not shown.Question D: what's is the probability of 30 or more seconds between vehicle arrival (to 4 decimals)?

The time between arrivals of vehicles at a particular intersection follows an exponential probability distribution with a mean of 13 seconds. a. Choose the graph of this exponential probability distribution. A. [f(x ) 0.09 0.08 0.07 0.06 -0.05 -0.04 0:03 0.02 0:01 12 18 24 B. [f(x ) 0.09 0.08 0.07 0.06 10.05 0:04 0.03 -0:02 12 18 24 X C. fox 0.09 -0.08 0.06 0.05 0.04 0.03 10.02 0:01 12 18 24 D. 0.09 +0.08 0:07 0.06- 0.05 0.04 -0.03 -0:02 0.01 12 24 4 X - Select your answer - 4 b. What is the probability that the arrival time between vehicles is 12 seconds or less (to 4 decimals)? c. What is the probability that the arrival time between vehicles is 6 seconds or less (to 4 decimals)
