You can do it this way, guessing order is important here so we use nPr
n=number of choices which is 6 digits/choices
r=the number of digits to pick
Therefore= 6P3 (Write this on your calculator)
Also the same as: 6x5x4, first 6 choices, then 5, then 3,without repeating anything
THE ANSWER WILL BE 120
