When tossing two pair of dice there are 36 possible outcomes.

1,6 - 2,6 - 3,6...

1,5 - 2,5 - 3,5...

1,4 - 2,4 - 3,4 ...

...

1,1

Continue pattern for all possibilities.

However getting a sum of 2 is only possible when each dice rolled is a 1.  This only oocurs one time in all of the possibilities.

The probability of rolling a total of 2 with 2 dice is `1/36.`

A die is a cube with the faces numbered from 1 to 6. When a fair die is tossed any of the numbers from 1 to 6 can turn up.

When 2 dice are thrown the total of the numbers on them is equal to 2 only if both the dice turn up 1.

The probability of two events A and B taking place simultaneously is the product of the probability of both the events A and B taking place.

P(A and B) = P(A)*P(B)

The probability of getting 1 when a die is thrown is 1/6. This gives the probability of the total when the two dice are thrown being 2 as (1/6)*(1/6) = 1/36.
