The probability that a bulb produced by a factory will fuse after certain period of time is 0.05. Find the probability that out of 5 such bulbs
a. P(None fuses) = 0.95^5 = 0.7738
----------------------------------------------
b. P(Not more than 2 fuse) = binomcdf(5,0.05,2) = 0.9988
----------------------------------------------
c. P(More than 2 fuse) = 1-0.9988 = 0.0012
