उत्तर
The number of possible outcomes is six: 1, 2, 3, 4, 5 and 6.
Among these numbers; 2, 4, 6 are the even numbers and 3, 6 are the multiples of 3.
Favourable outcomes are {2, 3, 4, 6}.
So, P (getting an even number or a multiple of 3) `=\text{Number of favouravle outcomes}/\text{Total number of all possible outcomes}=4/6=2/3`
