To find the probability of obtaining a multiple of 3, we need to determine how many numbers between 1 and 20 inclusive are multiples of 3.
The multiples of 3 between 1 and 20 are: 3, 6, 9, 12, 15, and 18.
There are 6 numbers that are multiples of 3.
Therefore, the probability is 6/20 = 3/10.
The answer is C. 3/10.
