There are 6 multiple choice questions in an examination. How many sequences of answers are possible, if the first three questions have 4 choices each and the next three he 2 each?

Explanation

The permutation of the first three questions are `(4)^3 = 64`


The permutation of the next three questions are (`2)^3 = 8`


The total permutation is `64 * 8 = 512.`


Therefore, 512 sequences of answers are possible
