Selina Aguirre · Answer 1

Since the problem is concerned of the arrangement in the first row, this can be solved through permutation. Above is a permutation of 14 taken 6 which can be easily solved through the calculator or through the equation,

14P6 = (14!) / (14-6) !

= 2162160

Thus, the answer is letter A.

Dashawn Good · Answer 2

This is a permutation problem with 14 elements that can only be taken 6 at a time. In permutation notation,

14P6

which in factorial form is

14! / (14 - 6) !

which is equal to

= 2162160

The answer is

2,162,160 different ways
