What is the probability of rolling a 1 or a 5 with 2 dice?

Answer 1

The odds are: 1 of 36

1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 2-1, 2-2, 2-3, 2-4, 2-5, 2-6, 3-1, 3-2, 3-3, 3-4, 3-5, 3-6, 4-1, 4-2, 4-3, 4-4, 4-5, 4-6, 5-1, 5-2, 5-3, 5-4, 5-5, 5-6, 6-1, 6-2, 6-3, 6-4, 6-5, 6-6

Each die is independent from the other (what you roll with one die does not affect what you can roll with the other). This means that each die can land on any number from 1-6. The sample set CAN involve duplicates, meaning a 1-2 is a DIFFERENT result than 2-1.

Since each die is independent from the other, we calculate the probability of each event happening, then multiple these probabilities by each other. The probability of each event is 1/6, or 0.167, so the changes of rolling double six is 0.0279 or 3%

Answer 2

On a standard six sided die, your chances of rolling ANY number would be one in six. It stands to reason that rolling two dice and getting any given number would be 2 in 6. It doesn't really matter that you want a five or a one or whatever, because your odds of rolling either (or both) would still be just 2 in six.

Answer:

If the question means "What are the odds of the total number of dots being 1 or 5", there are no ways of rolling a 1.

There are 4 numbers on the first die that are less than 5 and 1 complimentary number on the second die to make 5 for each of these. These are:

1+4, 2+3, 3+2, 4+1

There are 36 ways the dice could have come up.

So the odds are 4 out of 36, a five is likely to come up once in 9 rolls.

If the question is "What are the odds that either a 1 or a 5 willl show when two die are rolled", each die will show one of these numbers 2 times in 6 rolls, since there are 2 die in play, there are 4 chances in 6 rolls.
