The chance that any given bulb is on is equal to 1/2. The chance that all twenty bulbs are on at the same time is
Multiply all terms by 12/1 to get rid of fractions.
8x+2= -9x+12
Add 9x to both sides
17x+2=12
Subtract 2 from both sides
17x=10
Divide both sides by 17
x=10/17
Final answer: x=10/17
(x,y)
y does't change makes it easier
