Parallel Reliability

Problem

Reliability of a parallel system that works when at least one component works:

R = 1 - product(1 - reliabilities).

An empty list returns 0.0.

Hint

The system fails only when all components fail.

case 1

in: [[0.9,0.8]]

expected: 0.98

case 2

in: [[0.5,0.5]]

expected: 0.75

case 3

in: [[]]

expected: 0

case 4

in: [[1,0.3]]

expected: 1
