Larry is rolling two dice. His dad told him that he can skip doing the dishes that night unless he rolls double sixes. What is the probability...
A pair of dice are rolled. Find the probability for P(Not 2 or Not 12). P(Not 2 or Not 12) = 1 - P(2) - P(12) P(Not 2 or Not 12) = 1 - 1/36 -...
a 12 sided die is rolled find the probability of rolling a number greater than 7 We assume this is a fair die, not loaded. This means each side...
Sarah rolls 2 fair dice and adds the results from each. Work out the probability of getting a total that is a factor of 6. Factors of 6 are {6,...
A 6-sided die is rolled once. What is the probability of rolling a number less than 4? Using our one dice calculator, we get: P(N < 4) = 1/2
A dice has six sides. The dice is rolled once. What is the probability that a six will be the result. P(6) = 1/6
If two standard dice are rolled, what is the probability that the sum is 3? Using our 2 dice calculator, we get: 1/18
Probability of getting 4 or 6 when rolling a dice P(4 or 6) = P(4) + P(6) P(4 or 6) = 1/6 + 1/6 P(4 or 6) = 2/6 We can simplify this. We type...
A Pairs of fair dice is tossed. What is the probability of not getting a sum 7 or 8? Not a 7 or 8 means 2 - 6 or 9 - 12 Using our 2-dice...
Erik is rolling two regular six-sided number cubes. What is the probability that he will roll an even number on one cube and a prime number on the...
Write a sample space for rolling a dice twice Each die roll has 6 possible outcomes. So 2 die-rolls has 6^2 = 36 possible outcomes: 1,1 1,2 1,3...
2 fair sided die are rolled. How many ways can the dice be rolled to sum exactly 6? Using our 2 dice calculator, we get the following options:...
6 sided die probability to roll a odd number or a number less than 6 First, we'll find the set of rolling an odd number. From this dice...
Two dice are rolled. Enter the size of the set that corresponds to the event that both dice are odd. If dice 1 is odd, then we have the following...
A blue dice and a red dice are tossed what is the probability that a 6 will appear on both dice Each event is independent. P(Blue dice 6) = 1/6...
The sum is greater than 7, the sum is divisible by 2 2 dice sum greater than 7 means 8, 9, 10, 11, 12. Now take this set, and intersect it with...
