Answer:
The probability is calculated by the ratio of the number of favorable numbers over the total possible numbers. There are 6 favorable numbers: 3,6, 9,12,15 and 18.
The total possibilities are of course 20. So the probability of getting a multiple of 3 is 6./20 or 3/10. Provided that getting any number has equal chance.
