The description for the given question is described in the explanation section below.

Explanation:

Note that 20 programs or files are programmed into the storage at this time. The operating system is idle at a certain moment, waiting for both the I/O action by the 20 programs. Each system is estimated to be investing 80 percent (0.8) of the waiting period. Multiply the processing time among all 20 initiatives, to assess the likelihood.

⇒ 0.8 ^ 20 = 0.012

Assess the possibility of twenty services to assess the processing time utilization. Subtract the product of 20 programs from 1. To assess the likelihood.

⇒ 1 - 0.012 = 0.988

The CPU then spends 98.9 percent of its time on 20 applications.
