Question 1182619
the probability that a well, taken at random, will yield deposits of natural gas is .05.
the probability that it won't = 1 minus .05 = .95
the probability that 0 out of 6 wells will yield deposits of natural gas is equal to .95^6.
the probability that at least 1 will yield deposits of natural gas is 1 minus that = 1 minus .95^6 = .2649081094.
