probability that you removed 8 straight nails and 2 bent nails? To find the probability, first derive a general expression using the following notation:
N = Ns + Nbn = ns + nb
where is the total number of nails in the box, Ns and Nb are the number of straight and bent nails, respectively, is the total number of nails removed from the box, and ns and nb are the number of straight and bent nails removed from the box, respectively.
