The answer depends on the domain. If the selection is made from any real or rational numbers, the probability is 0. If the domain is all integers (or all positive integers) then the probability is 1/3. If it is some other subset of integers, then the answer is a rational number between 0 and 1/3.

EzraThe probability of getting a multiple of 3 depends on the total number of possible outcomes. For example, if you are rolling a fair six-sided die, there are two outcomes that are multiples of 3 (3 and 6), out of a total of six possible outcomes. Therefore, the probability of getting a multiple of 3 is 2/6 or 1/3.

What is the probability of getting a multiple of 3 when you roll a regular 6 sided die?
1 in 3
What is the probability of getting an odd number or a multiple of 3 when an unbiased die is tossed once?
The favourable outcomes are 1, 3, 5 or 6 so the probability is 4/6 = 2/3
What is the probability of getting a multiple of 3 or 4 in throwing a dice?
It depends on how many times you throw it! On a single throw, the answer is 0.5
What is the probability of getting a multiple of 5 when rolling 2 dice?
The probability is 7/36
What is the probability of flipping no heads when you flip three identical coins?
The probability of flipping one coin and getting tails is 1/2. In order to find the probability of multiple events occurring, you find the product of all the events. For 3 coins the probability of getting tails 3 times is 1/8 because .5 x .5 x .5 = .125 or 1/8.
