What is the probability of obtaining a sum of at least 6when rolling a pair of dice?
The best way to do this is to note that this is 1 minus the probability of obtaining a sum less than 6.
The probability of obtaining a 2 is 1/36 (both dice get 1)
The probability of obtaining a 3 is 1/18 (one dice gets 1, the other gets 2, or the other way around)
The probability of obtaining a 4 is 1/12 (both dice get 2, or one dice gets 1 and the other 3, or the other way around)
The probability of obtaining a 5 is 1/9 (one dice gets 2 and the other 3, or the other way around, or one dice gets 1 and the other 4, or the other way around)
Adding these probabilities up gives 5/18. 1 minus this is 13/18
Thus the probability of obtaining a sum of at least 6 when rolling a pair of dice is 13/18.

What is the probability of obtaining a sum of a least 4 when rolling a pair of dice?

Rolling three dice what is the probability of obtaining at least one six?
50%. There are three dice; each die has 6 faces.
When rolling two number cubes what is the probability of rolling at least one six?
When rolling two number cubes (standard six-sided dice), the probability of not rolling a six on a single die is 5/6. Therefore, the probability of not rolling a six on both dice is (5/6) × (5/6) = 25/36. To find the probability of rolling at least one six, we subtract this result from 1: 1 - 25/36 = 11/36. Thus, the probability of rolling at least one six when rolling two dice is 11/36.
When rolling one die 12 times what is the probability of rolling a 2?
The probability of rolling at least one 2 when rolling a die 12 times is about 0.8878. Simply raise the probability of not rolling a 2 (5 in 6, or about 0.8333) to the 12th power, getting about 0.1122, and subtract from 1.
When rolling a number cube twice what is the probability of rolling at least one even number?
one fourth
What is the probability of rolling a 1 with six dice?
The probability of rolling at least one '1' with six dice is 66.5% [1-(5/6)^6]*100%
What is the probability of tossing a coin 6 times and obtaining at least 3 consecutive heads?
The probability is 5/16.
If sixteen dice are rolled what is the probability of rolling at least one six?
It is 0.9459
What is the probability of getting 4 dots on top in rolling two dice?
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.
What is the probability of obtaining at least one head when a coin is flipped four times?
The probability of obtaining 4 tails when a coin is flipped 4 times is: P(4T) = (1/2)4 = 1/16 = 0.0625 Then, the probability of obtaining at least 1 head when a coin is flipped 4 times is: P(at least 1 head) = 1 - 1/16 = 15/16 = 0.9375
Right as a fraction and probability of rolling a three on a six sided dice?
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 rolling an even number with 3 dice?
With one roll of three dice, the probability is 7/8.
