2. CTfastrak bus waiting times are uniformly distributed from zero to 20 minutes. Find the probability that a randomly selected
Juliette [100K]

Answer:

b. 0.25

c. 0.05

d. 0.05

e. 0.25

Step-by-step explanation:

if the waiting time x follows a uniformly distribution from zero to 20, the probability that a passenger waits exactly x minutes P(x) can be calculated as:

P(x)=\frac{1}{b-a}=\frac{1}{20-0} =0.05

Where a and b are the limits of the distribution and x is a value between a and b. Additionally the probability that a passenger waits x minutes or less P(X<x) is equal to:

P(X

Then, the probability that a randomly selected passenger will wait:

b. Between 5 and 10 minutes.

P(5

c. Exactly 7.5922 minutes

P(7.5922)=0.05

d. Exactly 5 minutes

P(5)=0.05

e. Between 15 and 25 minutes, taking into account that 25 is bigger than 20, the probability that a passenger will wait between 15 and 25 minutes is equal to the probability that a passenger will wait between 15 and 20 minutes. So:

P(15
