Uniform (0,1) pdf. Figure 5.7 depicts the probability density function for the random number spinner for values between 0.0 and 1.0. This is the uniform probability density function for the range 0 to 1, denoted X, ~ uniform(0, 1). Use geometry to determine the following probabilities on this pdf.

(a) Pr(X ≤ 0.8)

(b) Pr(X ≤ 0.2)

(c) Pr(0.2 ≤ X ≤ 0.8)
