Answer 2

Answer:

720

Step-by-step explanation:

Alright, so we have 6 different digits, none of which is a zero.

In a five digit number, we obviously have 5 digits that means we have 5 places to fill.

For the first place, we can choose any one of the six so 6 possibilities

For the second place, we can use any one of the remaining five so 5 possibilities

Similarly, for the next places 4 possibilities then 3 and then 2

So total no. of numbers = 6×5×4×3×2 = 720

Hope it helps
