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.
