document.write( "Question 290629: I was trying to figure out a probability problem. Of 20 units in one lot. Each 20 unit lot has 10% defective items. what's the probability that the lot will be rejected? Accepted? Five or more items will in one lot is cause for rejection. I said it means there are at least 2 items in each 20 unit lot that is defective, which means the lot won't be rejected. I said it would be 0.05% chance it will be rejected and 0.95% chance it will be accepted. \n" ); document.write( "
