There are 2 possible answers. If you meant is either one of the dice land on a 1,
then the answer is 1/3. If you meant if they both ADD UP to 1, then it is impossible
and the answer is 0.
===========================================
The first answer accurately states the theoretical probabilities. But the question
clearly specifies "the experimental probability". That number is the result of an
experiment which, as far as we know, has not yet been perfrormed.
Also, in the parlance of frequent rollers, "rolling a (x)" means a roll of two dice
after which the sum of the spots showing on the top surfaces of both is (x).
It is 0.
If you're only rolling one die, it's a probability of 1 out of six, or 16.67%.
The probability of rolling either a 6 or 4 on one roll of a dice is two thirds (one sixth plus one sixth because both four and six have a probability of one sixth.
Rolling one die, it is 1/6. Rolling two dice, it is 2/6, which can be simplified to 1/3 or 33.33%.
The probability of rolling any single number of a regular die on one roll is one in six, or 1/6, or 0.166666....
With one roll of three dice, the probability is 7/8.
It is 0.
The probability of rolling at least one '1' with six dice is 66.5% [1-(5/6)^6]*100%
1/6
The probability of rolling a 4 in a die is 1 in 6, or about 0.1667. The probability, then, of rolling a 4 in at least one of two dice rolls is twice that, or 2 in 6, or 0.3333. The probability of rolling a sum of 4 in two dice is 3 in 36, or 1 in 18, or about 0.05556.
1/6
If you're only rolling one die, it's a probability of 1 out of six, or 16.67%.
When rolling one die, the probability of getting a 4 is 1 in 6, or 0.1667. If two dice are rolled, you get two unrelated chances of rolling at least one 4, so the probability is 2 in 6, or 0.3333.
The probability of rolling either a 6 or 4 on one roll of a dice is two thirds (one sixth plus one sixth because both four and six have a probability of one sixth.
If two dice are rolled once, the probability is 30/36 = 5/6
The probability of rolling a sum of 8 and doubles when rolling two dice is 1 in 36, or about 0.02778. Simply note that there are 36 permutations of two dice, of which exactly one of them (a 4 and a 4) matches the conditions specified.
Rolling one die, it is 1/6. Rolling two dice, it is 2/6, which can be simplified to 1/3 or 33.33%.
