Help I'm so bad at probability

 

When two fair $6$-sided dice are tossed, the numbers $a$ and $b$ are obtained. What is the probability that the two digit number $ab$ (where $a$ and $b$ are digits) and $a$ and $b$ are all divisible by $2$?

1 / 4 because 1 / 2 * 1 / 2 = 1 / 4

a has to be 2, 4, or 6

and b has to be 2,4, or 6

 

so yes,  0.5*0.5 = 0.25
