Answer

\frac{n!}{(n-k)!}$.

Here are the solutions to the problems:

Question 4: How many ways can you choose a president and secretary from a club consisting of 16 members? This is a permutation problem because the order of selection matters (President is different from Secretary). The formula for permutations is P(n,k)=n!(n−k)!P(n, k) = \frac{n!}{(n-k)!}.

  • a) With no restrictions We need to choose 2 positions (president and secretary) from 16 members. P(16,2)=16!(16−2)!=16!14!=16×15=240P(16, 2) = \frac{16!}{(16-2)!} = \frac{16!}{14!} = 16 \times 15 = 240 There are $\boxed

Here are the solutions to the problems: Question 4: How many ways can you choose a president and secretary from a club consisting of 16 members? This is a permutation problem because the order of selection matters (President is different from Secretary). The formula for permutations is P(n, k) = (n!)/((n-k)!). a) With no restrictions We need to choose 2 positions (president and secretary) from 16 members. P(16, 2) = (16!)/((16-2)!) = (16!)/(14!) = 16 × 15 = 240 There are $
