What is the probability of rolling a 3 on two consecutive rolls of a fair die round to the nearest 100

Assuming the die is six-sided. 

That means the probability for rolling a 3 on the first is 1/6, and rolling a 3 on the second is also 1/6. 
Multiply them together to get the probability of both rolling 3 consecutively. 
1/6 x 1/6 = 1/36 
In decimal form, this is 0.028 or 2.77%. 
Hope this helps!
