Question 248737: Suppose 39 newly created pairs of jeans are placed in a bin to be checked for quality. Of these, 4 will not be of high enough quality to sell. Suppose that two pairs of jeans are randomly selected, without replacement, from the bin. What is the chance that both pairs of jeans selected will be substandard? Please help me with this problem. Thanks! Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! nCr=n!/((n-r)!r!) Combination of n things taken r at a time.
.
4C2/39C2=6/741 chance of 2 substandard pair being selected.
