Examples (1) In a welding process, 10 different points of a battery tab are welded. If the probability of making an acceptable weld is 0.99, calculate: a) the probability of making a battery tab with 6 failed welds. b) the probability of making a battery with at least 2 failed welds.
An automatic spot-welding machine is used in an assembly plant. It is known that 5 percent of the welds made by the machine are defective. If 10 welds made by the machine are in spected at random, what is the probability of finding (a) no defective welds, (b) exactly one defective weld, (c) at least one defective weld, and (d) no more than one defective weld?

6) Smith is a weld inspector at a shipyard. He knows from keeping track of good and substandard welds that for the afternoon shift 5% of all welds done will be substandard. If Smith checks 300 of the 7500 welds completed that shift, what is the probability that he will find between 10 and 20 substandard welds?

Suppose there are 4 defective items in a lot (collection) of 60 items. A sample of size 15 is taken at random and without replacement. Let X denote the number of defective items in the sample. Construct the probability table and graph the probability mass function. In the sample, at least one defective item is detected. What is the probability that at most two defective items are found?
