Question

If pair of dice are rolled, what is the probability of getting (i) A total of 9. (ii) Same faces on both dices.​

Answer 1

Answer:

P(sum=9)= (Number of possible outcomes with the result of 4)/(Total number of possible outcomes) =

4/36 = 1/9

when two dice are thrown together then total number of all possible outcomes=

6^2 =6×6=36

The favorable outcome of getting the same number on both dice is: (1,1),(2,2),(3,3),(4,4),(5,5),(6,6).

Therefore,

The number of favorable outcomes = 6

Therefore,

Required probability= 6/36= 1/6
