What is the probability of rolling a die and getting an even number?
The probability of rolling an even number is three out of six, or three-sixths. This fraction can be simplified as the numerator and denominator are both divisible by three. Three divided by three is equal to one, and six divided by three is equal to two. This means that the answer, in its simplest form, is one-half.
When a dice is rolled the probability of a number which is even and greater than 4 is?
1 Expert Answer So in a single roll the probability of getting a number greater than 4 is 2/6 = 1/3.
What is the probability that the number rolled is an even number greater than 2?
Find the probability that one of the six possible numbers is an even number greater than two by dividing the number of possibilities by 6, or: 2 / 6 = 1 / 3.
What is the probability of getting an even number and a number greater than 3?
Calculate the probability of getting a number that is either even or greater than 3. So the probability that your roll is either going to be an even number OR a number greater than 3 is 1/2.
When a dice is rolled the probability of getting a prime number?
12
We can see from the above steps that the number of favourable outcomes where we get a prime number is 3 and the total number of possible outcomes i.e. the number of elements in the sample space is 6. Hence, the probability of getting a prime number is 12.
What is the probability of getting a 2?
Two (6-sided) dice roll probability table
Roll a… | Probability |
---|---|
2 | 1/36 (2.778\%) |
3 | 2/36 (5.556\%) |
4 | 3/36 (8.333\%) |
5 | 4/36 (11.111\%) |
What is the probability of rolling at least 4 or an odd number?
4 is one of the six possibilities, so the probablilty of rolling a 4 is 1/6. There are 3 even numbers up to and including six, as such the probablilty of rolling an even number is 3/6 or 1/2.
What is the probability of rolling a number greater than 3 and then rolling a 4?
Probability of rolling more than a certain number (e.g. roll more than a 5).
Roll more than a… | Probability |
---|---|
2 | 4/6 (66.67\%) |
3 | 3/6 (50\%) |
4 | 4/6 (66.667\%) |
5 | 1/6 (66.67\%) |
What is the probability of rolling a 4 on a die?
There are 2 even numbers greater than 2. That means the probability of rolling a 4 or 6, on a fair die, is 1/5 for rolling a 4 + 1/6 for rolling a 6 = 2/6 or 1/3. If a die is rolled, what is the probability that the number is greater than 4?
What is the probability of rolling a dice with 6 numbers?
If premise 2 above is true, then all six numbers have an equal chance of coming up on a given roll. The only two numbers that satisfy your condition (even and > 2), are 4 and 6. One of those will come up, in the long run, two rolls out of every six. 5. Thus the probability is 1/3. There is no such thing as “a dice.” “Die” is the singular.
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.
What is the probability of getting an even number greater than 2?
, worked teaching math at all levels from kindergarten to college for 55 years. the prob ability of getting an even number greater than 2 when rolling standard die must be 1/3. The reasoning is simple, 4 and 6 are the only two numbers out of the six possible numbers on the die that fit the requirements of the question.
