Two dice are thrown simultaneously the probability of obtaining a total score of 5 is?

Answer: Let E be the event of getting the sum of 5.

Total sample space available, i.e., total number of possible outcome n(S).

 First die
 123456
Second die11,11,21,31,41,51,6
22,12,22,32,42,52,6
33,13,23,33,43,53,6
44,14,24,34,44,54,6
 55,15,25,35,45,55,6
 66,16,26,36,46,56,6

also n(S)

=6×6 

=36 

Total number of possible outcome.
E = (1,4),(4,1),(2,3),(3,2)

So n(E) = 4

Hence probability of even E is, P(E)
