Best answer 2 votes 2 votes 6^4 because for every candy we have 6 choices (Permutation, Here order matters ) (6+4-1) C 4 = 126 (Combination with repetition, Here order doesn't matter ) Heisenberg answered Mar 18, 2017 selected Mar 18, 2017 by Shreya Roy Heisenberg comment Share Follow See all 0 reply Please log in or register to add a comment.
