How many of the triple permutations of the set A = {a,b,c,d,e} contain e?​​

Answer 1

6

Step-by-step explanation:

Assuming with triple permutations you mean permutations containing 3 elements of A:

{a,b,c} {a,b,d} {a,b,e} {a,c,d} {a,c,e} {a,d,e} {b,c,d} {b,c,e} {b,d,e} {c,d,e}

Every letter occurs 6 times.
