How many permutations exist of the letters a, b, c, d taken four at a time [Solved]

You have to apply factorials here and formulas. You have 4 letters which means that your n=4, and you have 3 objects at a time which, means that you have 4 different groups of combinations with 6 permutations in each due to the 3! factorial. 6 x 4 is 24.

Answer 6

Option A. 24 Step-by-step explanation: There are four letters a, b, c, d and we have to tell the permutations made when taken 3 at a time. This phenomenon exist = = = = 4! = 4 3 2 1 = 24 Therefore, option (A) 24 are the permutations exist.

4*3*2*1=24
