Answer 1

There are 36 possible outcomes with the two dice

 

Die 1     Die 2

1             1

1             2

1             3

...

6              4

6              5

6              6

 

Of those 36 possible combinations, only 2 will give you an 11 (5,6) and (6,5)

 

There are 6 possible combinations for 7

(1,6)

(6,1)

(2,5)

(5,2)

(3,4)

(4.3)

 

So your odds of getting a 7 or 11 are 8/36, or 2/9
