A single die is rolled twice. The 36 equally-likely outcomes are shown to the right. Find the probability of getting two numbers whose sum is 2 . The probability of getting two numbers whose sum is 2 is (Type an integer or a simplified fraction.)

Step 1 ：A single die is rolled twice. The 36 equally-likely outcomes are shown to the right.

Step 2 ：The only way to get a sum of 2 when rolling a die twice is to roll a 1 on both rolls.

Step 3 ：Since there are 6 possible outcomes for each roll, there are a total of \(6*6 = 36\) possible outcomes.

Step 4 ：The event of rolling a 1 on both rolls is just one of these outcomes.

Step 5 ：So, the probability of this event is \(\frac{1}{36}\).

Step 6 ：Final Answer: The probability of getting two numbers whose sum is 2 when rolling a die twice is \(\boxed{\frac{1}{36}}\).
