Sampling table : choose k object out of n Order matters Order doesn't Replace n^k n+k-1 C k Don't replace n*(n-1)*...*(n-k+1) n C k Pick k times from set of n objects, where order doesn't matter with replacement Extreme cases : k = 0 => n-1 C 0 = 1 Less extreme cases : k = 1 => n C 1 = n Simplest nontrivial examples: n = 2 => k + 1 C k = k .. 2022. 1. 11. 이전 1 다음
