The probability that the bulb is good is 12/15.
Since we have taken 1 item out the remaining total is now 14, so the probability of getting a defective bulb is now 3/14.
Now you multiply the probabilities together to get (12/15)(3/14)=(4/5)(3/14)=12/70=6/35
1/2 probability of 1 flip
1/2 x 1/2 x 1/2 x 1/2 = 1/16 probability

Trust me bro
That would be 8. first parenthesis, then multiply, then subtract.
