Answer 1

HEYA!!!

Here is your answer :
___________________________

Favourable outcomes = 11

{ (1,1),(1,2),(1,3),(1,4),(1,5),(1,6) 
         (2,1),(2,2),(2,3),(2,4),(2,5),(2,6) 
         (3,1),(3,2),(3,3),(3,4),(3,5),(3,6) 
         (4,1),(4,2),(4,3),(4,4),(4,5),(4,6) 
         (5,1),(5,2),(5,3),(5,4),(5,5),(5,6) 
         (6,1),(6,2),(6,3),(6,4),(6,5),(6,6) } 


Total outcomes = 36

Let E be the event to get the probability.

P ( E ) = Favourable outcomes / total outcomes

= 11/36
