How many ways can a person select 8 DVDs from a display of 13 DVDs?

To determine how many ways a person can select 8 DVDs from a display of 13 DVDs, we use the combination formula, which is given by ( \binom{n}{r} = \frac{n!}{r!(n-r)!} ). Here, ( n = 13 ) and ( r = 8 ). Thus, the number of ways to select the DVDs is ( \binom{13}{8} = \binom{13}{5} = \frac{13!}{5! \cdot 8!} = 1287 ). Therefore, there are 1,287 ways to select 8 DVDs from 13.
