Suppose that the reaction temperature x in certain chemical

Question

Suppose that the reaction temperature x in certain chemical process has a uniform distribution with a = -5 and b = 5 (refer to Exercise 19 for a description of a uniform distribution of a uniform distribution)

1. In the long run, what proportion of these reactions will have a negative value of temperature?
2. In the long run, what proportion of temperatures will be between -2 and 2? Between -2 and 3?
3. For any number k satisfying -5
