Select two numbers, n and k, each not higher than 12.
Number n should be greater than k, n>k,
like n=10 and k=3, or n=8 and k=2.
a) If car dealer has n different models of car and
each model goes in k different colors, in how many ways
you can choose your car?
b) In how many ways can you fill in k vacant positions
if you have n candidates (n>k). Order of selection makes a
difference, use formula for permutations.
c) In how many way can you select k books out of n books
on the shelf. Order of selection doesn’t matter, use formula for combinations
