If the students are A, B, C, D, E, F, G, H, and I, what is the probability that students A, B and C will be on the same team?
(A) 1/3
(B) 1/9
(C) 1/16
(D) 1/27
(E) 1/28
dont have OA, but i believe answer should be E am i right?
_ _ _| _ _ _ |A _ _ we have 8 options for B and we want B to be with A. so it has 2/8 chances to be with A = 1/4. now we want C to be with A and B. total positions for C is 7, it has only one position left to be with A and B so 1/7 chances. 1/4.1/7 = 1/28.
