A quality control inspection system requires that from each batch of items
a sample of 10 is selected and tested. If 2 or more of the sample are
defective the whole batch is rejected. If the probability of an item being
defective is 0.05 (20%)
(1) What is the probability of 2 defectives in the sample?
(2) What is the probability of the batch being rejected?
(Note: 0.955 = 0.7737、0.956 = 0.7350 、0.957 = 0.6983、0.958 = 0.6634 、
0.959 = 0.6302、0.9510 = 0.5987 )
(probability = 0.4) it can get $100,000. What should it do? (10%)
