What is the probability of rolling a 3 or 4 on a fair die?
Probability of rolling a certain number or less with one die
| Roll a…or less | Probability |
|---|---|
| 1 | 1/6 (16.667\%) |
| 2 | 2/6 (33.333\%) |
| 3 | 3/6 (50.000\%) |
| 4 | 4/6 (66.667\%) |
What is the probability of rolling a 4 or greater with a fair die?
Explanation: Number greater than 4 are 5 and 6 . So required probability is 26=13.
What are the possible outcomes if a fair die is rolled?
For example, when a die is rolled, the possible outcomes are 1, 2, 3, 4, 5, and 6. In mathematical language, an event is a set of outcomes, which describe what outcomes correspond to the “event” happening. For instance, “rolling an even number” is an event that corresponds to the set of outcomes {2, 4, 6}.
What is the probability that a fair die?
Standard Deviation of a Probability Distribution
| Fair Die | Loaded Die | |
|---|---|---|
| Roll | Probability | Probability |
| 1 | 1/6 | 1/12 |
| 2 | 1/6 | 1/12 |
| 3 | 1/6 | 1/3 |
What is the probability of rolling a 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.
When you roll a fair dice What is the probability that you obtain a 3 or a number less than three?
There are 6 total possible results, so the probability of rolling a number less than 3 is 26 or 13 or 0.3333 .
What’s a fair 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.
How many numbers are on a fair die?
A traditional die is a cube with each of its six faces marked with a different number of dots (pips) from one to six. When thrown or rolled, the die comes to rest showing a random integer from one to six on its upper surface, with each value being equally likely.
