What is the formula to find this? @kirbykirby @mathstudent55

mathstudent55 · Answer

The probability the first light is green is 0.59
The probability the second light is green is x.
The probability both light are green is 0.41 = P(first is green) * P(second is green)

mathstudent55 · Answer

P(second is green) = P(both green)/P(first green)
P(second is green) = 0.41/0.59
