Two dice are rolled Find the probability that the score on the dice is either 12 or at most 4?
The problem can be split into two parts, rolling a 12, or rolling a 4 or less. This can be further broken down to rolling a 2, rolling a 3, rolling a 4, or rolling a 12.
P(rolling 4 or less, or 12) = P(rolling 4 or less) + P(rolling 12) = P(rolling a 2) + P(rolling a 3) + P(rolling a 4) + P(rolling a 12) = 1/36 + 2/36 + 3/36 + 1/36 = 7/36

Find the probability of each event when two fair number cubes are rolled?
The probability that any number will come up on one cube is 1/6. 1/6*1/6=1/36 the probability is 1/36
How do you use a z table?
A z table is used to calculate the probability of choosing something that is normally distributed. In order to use it, first a z score is needed. A z score is the number of standard distributions a value is away from the mean of the data. In order to find the z score, take the value of the datum, subtract the mean, then divide by the standard deviation. The result is a z score. Look up the z score on the table to find the probability of getting anything equal to or lesser than the value you chose.
When two dice are rolled find the probability of getting a sum of 5 or 6?
There are 36 permutations of two dice. Of these, 9 have a sum of 5 or 6, so the probability of rolling a sum of 5 or 6 on two dice is 9 in 36, or 1 in 9, or about 0.1111.
What is a probability of an event?
Lets first start by defining some terms:Probability (P) in statistics is defined as the chance of an event occurring.Probability experiment is a chance process that leads to results called outcomes.An outcome is the result of a single trial of a probability experiment.A sample set is the set of all possible outcomes of a probability experiment.An event consists of a set of outcomes of a probability experiment. An event can be one outcome or more than one outcome. The event can be anything from flipping a coin, to rolling a die, to picking a card.The probability of any event (E) is:(# of outcomes in E) / (total # of outcomes in sample space)For example: Find the probability a die is rolled and you get a 4?We know that there are 6 possibilities when rolling a die. We can either rolled a 1, or a 2, or a 3, or a 4, or a 5, or a 6.Using the equation above:P(rolling a 4)= 1/6The event in this case is rolling a 4.
How do you find experimental-probability?
To find the experimental probability of an event you carry out an experiment or trial a very large number of times. The experimental probability is the proportion of these in which the event occurs.
If two dice are rolled Find the probability that the score on the dice is either 7 or 9?
5 out of 12
When a die is rolled find the probability of getting a 5?
the probability is 1 out of 6
When a die is rolled find the probability of getting a a number larger than 2?
If it is a fair die that is rolled once, then the probability is 2/3.
Find the probability of getting a number greater than 5 when a die is rolled one time?
The probability is 1/6.
When two dice are rolled find the probability that the sum is a multiple of 3 or greater than 4?
The probability is 35/36.
When 2 dice are rolled find the probability of getting a sum of 10 or doubles?
The probability is 8/36 or 2/9
When two dice are rolled find the probability of getting a 6 or 7?
Probability that the sum is 6 = 5/36 Probability that the sum is 7 = 6/36
A single fair die is rolled find the probability of getting a 1?
It is 1/6.
When two dice are rolled find the probability of getting a sum less than 13?
Assuming these are regular dice, the probability is 1.
When two fair dice are rolled find the probability that the sum is even and greater than 8?
Probably.
A pair of dice are rolled find the probability at least one dice is a 4?
When rolling one die, the probability of getting a 4 is 1 in 6, or 0.1667. If two dice are rolled, you get two unrelated chances of rolling at least one 4, so the probability is 2 in 6, or 0.3333.
When two dice are rolled find the probability of getting a sum of 10?
There is an approximately 8% chance of that, or 1 out of 12.
