(iii) So, Favorable outcomes i.e. to get a multiple of $3$ are $3,6,9,$ and $12$
Therefore, total number of favorable outcomes i.e. to get a multiple of $3$ is $4$
We know that the Probability = Number of favorable outcomes/ Total number of outcomes
Hence, the probability of getting multiple of $3=4/12=1/3$
(iv) Now, Favorable outcomes i.e. to get an even number are $2,4,6,8,10,$ and $12$
Therefore, total number of favorable outcomes i.e. to get an even number is $6$
We know that the Probability = Number of favorable outcomes/ Total number of outcomes
Hence, the probability of getting an even number $=6/12=1/2$
