Frequent question: What is the probability that the numbers on two dice are equal?

If the two dice are fair and independent , each possibility (a,b) is equally likely. Because there are 36 possibilities in all, and the sum of their probabilities must equal 1, each singleton event {(a,b)} is assigned probability equal to 1/36.

What is the probability of getting same number on two dice?

The probability of rolling a specific number twice in a row is indeed 1/36, because you have a 1/6 chance of getting that number on each of two rolls (1/6 x 1/6). The probability of rolling any number twice in a row is 1/6, because there are six ways to roll a specific number twice in a row (6 x 1/36).

What is the probability that the sum of 2 dice is even?

Of the 36 results from throwing 2 six sided dice, exactly 18 out of 36 outcomes are even (even sum of the 2 dice), so your odds are 50%, or 1/2. Originally Answered: Two dice are thrown simultaneously.

What is the probability of rolling a 3 twice?

Since the occurrence of 3 on first roll is independent of the occurrence of an odd number on the second roll, Probability of complete event =(probability of showing a 3 on the first roll) x (probability of an odd number on the second roll)=1/6×1/2=1/12.
