You are asked to take a sample of 30 purchasing records for an audit. Historical data show that on average 5% of the records had problems associated with them. Each record can have only 0 or one problem. What is the probability of observing 1 or more problems in the sample of 30? (Hint: first figure out what distribution it is. Second write it down as Pr(X>0) and then enter the p value and n into the spreadsheet and read the appropriate probability).

a 0.79

b 0.74

c 0.22
