Expected Value Decision Threshold

Problem

Compute the break-even probability for acting: cost / value.

Return 0.0 when value <= 0.

Hint

Above the break-even probability the action has positive expected value.

case 1

in: [2,10]

expected: 0.2

case 2

in: [5,5]

expected: 1

case 3

in: [0,10]

expected: 0

case 4

in: [3,0]
