What is the probability of getting a number that is at most 4?
Probability of rolling a certain number or more.
Roll a…or more | Probability |
---|---|
1 | 6/6(100\%) |
2 | 5/6 (83.333\%) |
3 | 4/6 (66.667\%) |
4 | 3/6 (50\%) |
What is the probability of throwing one dice and getting the number greater than 4?
1 Expert Answer If you roll a single die there are 6 possible outcomes (1,2,3,4,5,6), 2 of which are greater than 4. So in a single roll the probability of getting a number greater than 4 is 2/6 = 1/3.
What is the probability of rolling a number less than 3 on a 6 sided die?
Assuming you mean a standard fair 6-sided die… The probability of rolling a number less than 3 (so, 1 or 2) is 2 out of 6, or 1/3.
What is the probability of rolling a dice and getting a number greater than 2?
The probability that that the number obtained is greater than 2 is the no. of outcomes when the number is greater than 2 divided by the number of possible outcomes. So, the probability here is 4/6 that is 2/3. So, when a dice is thrown once then the probability that the number is greater than 2 is 2/3.
What is the significance of rolling two dice in probability?
Rolling two dice always plays a key role in probability concept. Whenever we go through the stuff probability in statistics, we will definitely have examples with rolling two dice. Look at the six faced die which is given below. The above six faced die has the numbers 1, 2, 3, 4, 5, 6 on its faces.
What is the probability of rolling a 6 on a die?
Roll the die six times, and the probability of not rolling a 6 is 5 6 ⋅ 5 6 ⋅ 5 6 ⋅ 5 6 ⋅ 5 6 ⋅ 5 6, also written (5 6)6, which = 33.5\%. Therefore, the probability of rolling a 6 at least once in 6 rolls = 100\% −33.5\% = 66.5\%
What is the probability of a 27 on a 10-sided dice?
Taking into account a set of three 10 sided dice, we want to obtain a sum at least equal to 27. As we can see, we have to add all permutations for 27, 28, 29, and 30, which are 10, 6, 3, and 1 respectively. In total, there are 20 good outcomes in 1,000 possibilities, so the final probability is: P (X ≥ 27) = 20 / 1,000 = 0.02.
How many elementary events are there in a dice roll?
In the present case, since a dice results in 6 outcomes and the dice is rolled twice, total no. of outcomes or elementary events is 62 or 36. We assume that the dice is unbiased which ensures that all these 36 elementary events are equally likely.
