You can use a multiplication table to help you visualize the answer. Simply only focus on the values 1-6.
Looking at a multiplication table, there are 36 possible values that the two dice can multiply to, but there are only 4 possible ways to get 25 or more (5*5=25, 5*6=30, 6*5=30 and 6*6=36)
So the probability that the product is 25 or more is which is 0.1111 in decimal form (basically, an 11.11% chance)

The only suiting combinations are 6 x 6, 5 x 5, 6 x 5, and 5 x 6, out of 36 possible combinations, so the probability is
