Answer:

0.985

Explanation:

A system contains three components that are arranged in parallel, they include 0.9, 0.7 and 0.5

Therefore the system reliability can be calculated as follows

= 1 - (1 -0.9)×(1-0.7)×(1-0.5)

= 1 - 0.1×0.3×0.5

= 1 - 0.1×0.15

= 1 -0.015

= 0.985

Hencd the system reliability is 0.985
