What is the probability of rolling a 2 on the roll on a die?
If it's a six-sided die (like the kind used in craps and most dice games) the odds are 1 in 6.The probability of rolling a single number on any kind of die* is 1 ÷ (the number of sides).*Except, of course, for weighted, shaved, or otherwise illegal dice.
What is the volume of a rectangular prism that is constructed of inch cubes?
The answer is the number of inch cubes used in the construction.
What number can be used to describe the probability of an impossible event?
The probability of an impossible event is 0 (zero).
What is used to determine the probability of two indepepdent events occurring?
Multiply together the probability that each event would have of occurring by itself. For example, the probability of rolling a "3" on a single die is 1/6 ,because there are 6 different possibilities. And the probability of flipping a "heads" on a coin is 1/2 , because there are two possibilities. Then the probability of rolling a "3" AND flipping a "heads" is ; 1/6 x 1/2 = 1/12 .
What is the equation used to determine probability in what ways can probability be expressed?
Probability = number of times an event is expected to happen / number of opportunities for an event to happen It can be expressed as a percentage or a fraction.

What is the prbability of rolling a five on one die three times in a row?
The chance is one in 216 (6^-3).The probability of rolling a five once is 1/6. Rolling a five again, on the same die or another, will still have a 1/6 chance. Therefore, the probability of the event occurring twice is 1/36 (1/6^2). Three times has a probability of 1/216 (1/6^3), and so on. It does not matter what die is used, as long as it has six sides.The probability p of rolling a number x times consecutively on an s sided die isp=s^-x

What is the relationship between statistics and probability?
Probability is used to answer questions in the category of Statistics. Probability is a basic statistic that gives numeric value to the questions; Will a specific event occur? or How certain are you that it will occur. Probability of rolling a 3 on a 6-sided die is 1/6.
How does the experimental result differ from the theoretical in terms of accuracy?
Provided that the correct model is used, the theoretical probability is correct. The experimental probability tends towards the theoretical value as the number of trials increases.Provided that the correct model is used, the theoretical probability is correct.

What is the probability that you will spin a 4 and roll a 4?
Assuming each possible number on a spinner has the same probability and an unbiased die is being rolled, the answer depends on how many numbers are on the spinner, and how many times the number 4 appears on each.To find the probability, workout the probability of spinning a 4 on the spinner and the probability of rolling a 4 on the die; then as spinning the spinner has no effect on rolling the die, they are independent events and to get the probability of both happening multiply them together.The probability of success is the number of successful outcomes divided by the total number of outcomes, giving:Probability(spinning a 4) = how_many_4s_are_on_the_spinner / how_many_numbers_are_on_the_spinnerProbability(rolling a 4) = how_many_4s_are_on_the_die / how_many_numbers_are_on_the_dieProbability(spinning a 4 and rolling a 4) = Probability(spinning a 4) × Probability(rolling a 4)Examples:an octagonal spinner with the numbers 1-4 on it each twice and a tetrahedral die (as used in D&D games) with the numbers 1-4 on it→ pr(spin 4 & roll 4) = 2/8 × 1/4 = 1/16a decagonal spinner with the numbers 0-9 and a tetrahedral die with the numbers 0-3 on it→ pr(spin 4 & roll 4) = 1/10 × 0/4 = 0a decagonal spinner with the numbers 0-9 and a standard die with the numbers 1-6 on it→ pr(spin 4 & roll 4) = 1/10 × 1/6 =1/60

What operation is used when calculating the probability that 2 events will happen and Find the theoretical probability of rolling a total of 7 as a sum of two dices?
If the two events are unrelated, as they are in rolling two dice or one die twice, simply multiply the probabilities together. However, you also have to consider the permutations involved in rolling dice and realize that there is more than one way to roll a particular sum. There are 36 permutations of rolling two dice. Of these, exactly one has a sum of two, the the probability of rolling a sum of two is 1 in 36, or about 0.02778. You simply multiply 1 in 6 by 1 in 6, getting 1 in 36. In the case of rolling a sum of seven, there are exactly six permutations, 1+6, 2+5, 3+4, 4+3, 5+2, and 6+1, so the probability of rolling a sum of seven is 6 in 36, or 1 in 6, or about 0.1667. Another example is rolling pairs, such as two's or three's. The probability of rolling "something" on one die is 1 in 1, while the probability of matching it on the second die is 1 in 6, so you multiply (1 in 1) by (1 in 6) to get a probability of rolling a pair of 1 in 6, or about 0.1667. More useful towards understanding this concept is a deck of 52 cards. The probability of drawing an Ace is 4 in 52, or 1 in 13, or about 0.07692. The probability of drawing two Ace's is (4 in 52) times (3 in 51), or 12 in 2652, or 1 in 221, or about 0.004525. In this case, the two events are related, because the occurrence of the first event affects the probability of the second event, so you need to consider the calculation carefully.
