I'm going to assume this is a cube die?

 

1) 1/1 , 1/6 , 1/6 = 1/1*6*6 = 1/36

2) 5/6 . 5/6 , 5/6 = 5*5*5/6*6*6 = 125/216

3) 1/2 , 1/3 , 1/6 (considering that 2 , 4 , and 6 are your even numbers) = 1/2*3*6 = 1/36

1. p = 1*(1/6)*(1/6) = 1/36

2. p = (5/6)*(5/6)*(5/6) = 125/216

3. p = (1/2)*(1/3)*(1/6) = 1/36
