2. A steel plate contains 20 bolts. Assume that 5 bolts are not torqued to the proper limit. 4 bolts are selected at random, without replacement, to be checked for torque. If an operator checks a bolt, the probability that an incorrectly torqued bolt is identified is n. If a checked bolt is correctly torqued, the operator's conclusion is always correct. What is the probability that at least one bolt in the sample of four is identified as being incorrectly torqued?

e.g. Student ID=61190003 average=D((6+1+1+9+0+0+0+3)/8) × 0.01 = 20/8 = 2.5 then round the
number to an lower integer t [2.5] = 2; n = 1- (2 mod 5)/5 = 2/5 = 0.4
