Answer

Answer:

(a) 0.40 (b) 0.85

Explanation:

Step1: Identify relevant regions for (a)

Region A corresponds to numbers between 1 and 5.

Step2: Determine probability for (a)

The area of region A is 0.40, so probability is 0.40.

Step3: Identify relevant regions for (b)

Regions A and B correspond to numbers between 1 and 8.

Step4: Calculate probability for (b)

Add areas of A and B: $0.40 + 0.45=0.85$.
