You can put this solution on YOUR website! A sample of 4 different calculators is randomly selected from a group containing 17 defects and 36 with no defects. What is the probability that at least 1 of the calculators id defective?
------------------------------------
Binomial Problem with n = 4 and p(defect) = 17/53 ; p(no defect) = 36/53
------------------------------------
P(>=1 defect) = 1-P(no defects) = 1 - (36/53)^4 = 0.7871
