Series Reliability

Problem

Reliability of a series system where every component must work:

R = product of reliabilities.

An empty list returns 1.0, since there is no component to fail.

Hint

Independence lets you multiply the component reliabilities.

case 1

in: [[0.9,0.8]]

expected: 0.7200000000000001

case 2

in: [[0.5,0.5,0.5]]

expected: 0.125

case 3

in: [[]]

expected: 1

case 4

in: [[1,0.4]]
