No. of all possible outcomes when 3 dice are rolled = 6 x 6 x 6 = 216

 

Sum of 5 can be obtained when we have (1,1,3), (1,3,1), (3,1,1); (1,2,2), (2,1,2), (2,2,1) i.e. in 6 ways

 

Thus probability of getting sum 5 is = 6 / 216 = 1/36
A paradox is an argument that starts with apparently acceptable assumptions and leads by apparently valid deductions to an apparent contradiction. Since logic admits no contradictions, either the apparently acceptable assumptions are not acceptable, or the apparently valid
deductions are not valid, or the apparent contradiction is not a contradiction. A paradox moves us to reexamine the argument until we find out what is wrong.
