Question

A dice is tossed once find the probability of getting an even number or a multiple of 3

Answer 1

3/6=1/2. 2 , 4, 6 are even nos. i.e.it has 3 nos.
2/6=1/3. 3 and 6 are only multiple of 6 of 3 in a dice i.e it has only 2 nos.

Answer 2

possible outcomes ={ 1,2,3,4,5,6} no.=6

favorable outcomes = {3,6} no.=2

∴Probability = no. of favorable outcomes / no. of possible outcomes

                    =2/6

                    = 1/3 (simplified)
