Dice rolling odds help, please?

What are the chances of rolling 3 dice, and getting 1 or more 6's?

And what are the chances of rolling 3 dice, and getting 2 or more 6's?

By "6", I mean a side with 6 dots, not a total of 6.

Thanks!

    P[x=>1]=1-P[x=0] where x is the amount of 6's rolled

    1-P[x=0]=1- (5/6)^3 = 0.421

    P[X=2 or X=3]=P[X=2]+P[X=3]= 3 nCr 2 (1/6)² * 5/6 + (1/6)^3 = 0.074
