4.58 Find the probabilities. Let the random variable X be a random number with the uniform density curve in Figure 4.9 (page 240). Find the following probabilities:

1. (a) P(X ≥ 0.35).

2. (b) P(X = 0.35).

3. (c) P(0.35 < X < 1.35).

4. (d) P(0.18 ≤ X ≤ 0.25 or 0.4 ≤ X ≤ 0.5).

5. (e) X is not in the interval 0.4 to 0.8.
