A lot of 50 spacing washers contains 30 washers that are thicker than the target dimension. Washers are selected from the lot at random without replacement.
(a) What is the minimum number of washers that need to be selected so that the probability that all the washers are thinner than the target is less than 0.10?
(b) What is the minimum number of washers that need to
be selected so that the probability that 1 or more washers are
thicker than the target is at least 0.90?
