I am ready to be the first one to get it wrong again, mandy ...

Is that 30 ?

for the first dice, you can choose any of the 6 numbers,

for the second one, you can only one of 5 remaining numbers,

the the third one, you can only choose one - the same as the second dice.

That makes it: 6x5x1 = 30
