Suppose that a classroom has 4 sets of lights. The probability that one of the lights work is 0.6. Suppose that each light works independently of the others. What is the probability that none of the lights work? Round your answer to two decimals places.
------------------------------------------------
The problem is binomial with n=4, p=0.6 ; x = 0
-------------------------------------------------
P(x=0) = 4C0*(0.6)^0*(0.4)^4 = 1*1*0.0256 = 0.0256
