    1. If the dice are rolled together then there isn't a 'first' and a 'second' dice. As such, it doesn't matter which of them comes up with a '2'. The probablity of either of them being a '2' is 1/3. The probability of the other one being a '5' is 1/6, so the probability of one being a '2' and the other being a '5' is 1/3 x 1/6 = 1/18.

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