How many times will you get a six if you throw a dice 100 times?
(a) if a fair die is rolled 100 times, how many 6’s do you expect? the probability of rolling a 6 on a fair die is 1/6, so that we expect 100 × 1/6 = 16.7 ≈ 17 6’s to be rolled.
How many ways can you roll a 6 sided dice?
1 Expert Answer Each die has numbers 1-6 (that is, 6-sided). There are 36 possible outcomes.
What are all the possibilities when rolling a fair six sided die?
Rolling two six-sided dice: Each die has 6 equally likely outcomes, so the sample space is 6 • 6 or 36 equally likely outcomes….
| First coin | Second coin | outcome |

What is a fair six-sided dice?
At its simplest, a fair die means that each of the faces has the same probability of landing facing up. A standard six-sided die, for example, can be considered “fair” if each of the faces has a probability of 1/6.
When you roll a fair 6 sided die find the odds that you will roll a 2 or an odd number?
1/4
Summary: If you roll two fair six-sided dice, the probability that both dice show an odd number is 1/4.
How many outcomes are there such that all of the dice are different numbers?
When you roll just one die, there are six different ways the die can land. When two dice are rolled, there are now 36 different and unique ways the dice can come up. This figure is arrived at by multiplying the number of ways the first die can come up (six) by the number of ways the second die can come up (six).
How do you find the probability of rolling a single die?
The probability of rolling the same value on each die – while the chance of getting a particular value on a single die is p, we only need to multiply this probability by itself as many times as the number of dice. In other words, the probability P equals p to the power n, or P = pⁿ = (1/s)ⁿ.
What is the probability of Rolling 3 dice with different numbers?
There are 216 possible ways that three dice can be rolled (6 x 6 x 6). We can calculate the probability of them all being the same, easily, as 1/6 x 1/6 = 1/36 (The second die matches the first 1 time in 6, and the third die matches, again, 1 time in 6).
What is the probability of getting a Yahtzee in a single roll?
The probability of getting a Yahtzee in a single roll is easy to calculate. There are five dice, so whatever the first die rolls there is a 1/6 chance that the second die is the same number. If that occurs, there’s a 1/6 chance that the third die is the same, ditto the fourth and the fifth.
What is the probability of getting 7 on a 10-sided die?
There is a simple relationship – p = 1/s, so the probability of getting 7 on a 10 sided die is twice that of on a 20 sided die. The probability of rolling the same value on each die – while the chance of getting a particular value on a single die is p, we only need to multiply this probability by itself as many times as the number of dice.
