Find the probabilities specified in each of the parts of given Exercise.
Exercise
Draw the density curve corresponding to each of the following random variables, and then shade the area corresponding to the desired probability. You do not need to compute the probability.
a. X is a uniform random variable from 10 to 20, P(10 ≤ X ≤13).
b. X is a uniform random variable from 0 to 20, P(X ≤ 5).
c. X is a uniform random variable from 0 to 8, P(X ≤ 4).
