can you show me how to start

Prob(2, then another 2) = 2/6 * 2/6 = 1/9
Prob(red,white,yellow) = 4/6 * 1/6 * 1/6 = 1/54

these are the answers for them

For the first one there are 6 possible numbers, two of which are 2. So the probability of rolling a 2 is 2/6.
If these are independent then the probability of throwing another 2 is also 2/6.
The probability of the combined two events is the product of the probabilities thus
2/6*2/6 = 1/9
The same approach is taken for the coloured sides.
