(b)What is the probability that the arrival time between vehicles is13seconds or less?

As with all other distributions, the entire area under the curve will sum to 1. This area is also referred to as the cumulative probability and the formula to find the area is given below where

x₀

is a specific value of the random variablex.

P(xx₀) = 1e^x₀/

Here, we want to find the probability that the arrival time between vehicles is13seconds or less. Thus,

x₀= __________________ and the probability statement is P(x _______________)
