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 $
