उत्तर
When a die is thrown, the possible outcomes are 1, 2, 3, 4, 5 and 6.
Thus, the sample space will be as follows:
S = {1, 2, 3, 4, 5, 6}
Let A be the event of getting a two or four.
Two or four occurs once in a single roll.
Therefore, the total number of favourable outcomes is 2.
Hence, the probability of getting 2 or 4 is as follows:
P(A) = \[\frac{2}{6}\]
= \[\frac{1}{3}\]
