Q3 of 158 Page 34

Two dice are thrown simultaneously. The probability of obtaining a total score of 5 is

As 2 dice are thrown so there are 6×6 = 36 possibilities.


Let E denote the event of getting a total score of 5.


E = {(1,4),(2,3),(3,2),(4,1)}


∴ n(E)=4


Hence,


P(E) = 4/36 = 1/9


As our answer matches only with option (c)


∴ Option (c) is the only correct choice.
