#### In a single throw of a die we can get any one of the six numbers 1, 2, ..., 6 marked on its six faces. Therefore, the total number of elementary events associated with the random experiment of throwing a die is 6.

Let A denote the event "Getting 3 or 4"

Clearly, A occurs when we get either 3 or 4 as an outcome.

∴ Favourable number of elementary events = 2.

Hence, P(A)=26=13
