一道超搞的英语数学题~有急用~
A sets of elements that is taken without regard to the order in which the elements are arranged is called:A:sequence B:permutation C:combination D:progresstion

一道超搞的英语数学题~有急用~A sets of elements that is taken without regard to the order in which the elements are arranged is called:A:sequence B:permutation C:combination D:progresstion
答案是C
combination
组合
permutation是排列

C
sequence序列permutation排序
combination组合progresstion (不知道)
无顺序的提取元素就是选组合啦
