Unformatted text preview: e answer to our problem. There are C(48, 5) ways to pick the 5 socks. Then for the numerator, there are C(8,5) ways to choose 5 different colors of socks and then 6 5 ways to choose 5 socks, one of each of the chosen colors (to avoid a pair). So we get, ⎛ 8⎞ 5 ⎜ 5⎟ 6 ⎝⎠ 1− ⎛ 48 ⎞ ⎜ 5⎟ ⎝⎠ 3. (a). How many subsets of the ten- element set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} are disjoint from A = {0, 1, 2} or disjoint from B = {2, 3}? Solution: This is the number of subsets disjoint from...
