What is the probability of rolling at least one 4 on the three dice?
Outcomes containing at least one occurrence of 4 when rolling 3 dice: Therefore, 91 of the 216 possible 3 dice roll outcomes contain at least one (4).
What is the probability of at least four?
“At least” 4 hits implies 4 or 5 hits. The area of the bull’s-eye is 9π and the area of the entire target is 81π. The probability of hitting the desired bull’s-eye is 1/9.
What is the probability of rolling at least one?
Explanation: The probability of rolling at least one “1” if you roll a dice six times is the same as 1 minus the probability of rolling zero 1s if you roll a dice six times. The probability of not rolling a 1 if you roll a dice once is 5/6.
What’s the probability of rolling at least one 3 Given n die?
On the first die you roll, there is a 1/6 chance of getting a 3. The probability of NOT rolling a 3 with one die is 5/6 so the probability of NOT rolling a 3 with a roll of two dice is 25/36. The probability of rolling at least one 3 is 1–25/36=11/36, a bit less than 1/3.

What is the probability of not rolling any 6’s in four rolls of a balanced die?
a) Consider the complement problem, there is a 5/6 probability of not rolling a six for any given die, and since the four dice are independent, the probability of not rolling a six is (5/6)4 = 54/64 = 625/1296.
What does at least mean in probability?
At least also means “less than or equal to”. Therefore, in probability, at least mean the minimum value that should occur once a random event happens.
How do you find the probability of at most one?
The easy way to do it: the probability that at most one event will occur is the same as the probability that not both will occur, that is, 1−P(A∩B) .
