What is the probability of getting a factor of 6 when you have 1 2 3 4 5 6

Hello,

I suppose you mean using all those digits one time.

The sum of the digits is a multiple of 3.

Every number formed with those digits is a multiple of 3.

To be divisible by 2, the number must end with an even digit (2,4,6)

So probability is 3/6=1/2
