On a standard die, there are two numbers greater than 4, 5 and 6. 5 and 6 make up 2/6 of a die, or 1/3. So the probability of getting 5 or 6 once is 1/3 then to find the probability of doing it twice in a row, multiply 1/3 by 1/3( its the same number because there is no innate difference in the rolls). 1/3*1/3=1/9.
