totoal probability that all bulbs are not blown away is
(1-p) ^ n ...
so probability that atleast one blown away = total probability that all bulbs are blown away = 1 - (1-p)^n
I'm a new one in this forum. This forum looks pretty informative to me. Trying to ask your favor...Is anybody who can solve the following? I'm trying to solve the following.
There are "n" bulbs wired in line so that if any one bulb is dead, all "n" bulb will not light up accordingly. Assuming a probability "p" that one bulb is blown or dead, what is a probability that all "n" bulbs will not light up? The probability "p" is equivalent to all "n" bulbs.
