use binomial probability. (nCx)(px)(qn-x)...... N=trials x=outcomes p=probability in one trial. q=1-p...... N=20 x=4 p=1/6 q=5/6.......... nCx or nCr is a function on any scientific calculator, may need to search for it..
(20C4)(1/6)4(5/6)16=.2022 or 20.22%

The above probability is the theoretical probability. The experimental probability would be: P(3) = 4/20 = 0.20 = 20%.

What is the question of the problem if rolling a number cube labeled from 1 to 6 and the probability is 12?
The probability of any event is always a number from 0 to 1, inclusive. It can never be 12.
What is another name for Experimental Probability?
Another name for experimental probability is empirical probability. This is the ratio of the number of outcomes in which a specified event occurs to the total number of trials.
What is the experimental probability of rolling a 2 on a number cube rolled 50 times?
Conduct the following experiment: Roll a number cube 50 times. Count the number of times you roll a 2. Divide that number by 50. That is the experimental probability. The answer that I might get may well be different to yours. And if you do you experiment another time, the answer is likely to be different.
What is the experimental probability of rolling 3 or a 4 on a number cube?
The experimental probability of rolling a 3 or a 4 on a number cube cannot be stated here, because it depends on the actual results of a set of trials, results which will vary for each set of trials.Roll a die 10 times and see what you get. Do it another 10 times, and you should see different results.The theoretical probability, however, is well known - it is 2 in 6, or 1 in 3, or about 0.3333.
Experimental probability of rolling the sum of 2?
That means that you should roll a die many times, count how often you get the number "2", then divide this by the total number of rolls. If the die is "fair" (no extra weight on one side), you would expect this experimental probability to be somewhere close to the theoretical probability of 1/6, at least, if you roll often enough.
What is the question of the problem if rolling a number cube labeled from 1 to 6 and the probability is one half?
There could be many questions: What is the probability of rolling an even number. What is the probability of rolling an odd number. What is the probability of rolling a number less than 4. What is the probability of rolling a number more than 3. What is the probability of rolling 1,4, or 6. Basically it could be any question about the probability of rolling half of the faces.
What is the experimental probability of rolling an even number?
The experimental probability of anything cannot be answered without doing it, because that is what experimental probability is - the probability that results from conducting an experiment, a posteri. This is different than theoretical probability, which can be computed a priori. For instance, the theoretical probability of rolling an even number is 3 in 6, or 1 in 2, or 0.5, but the experimental probability changes every time you run the experiment.
What is the probability of rolling an even number on a number cube labeled 1 through 6?
1/2 - you have a 50-50 chance of rolling an even number (or an odd number for that matter !)
What is the question of the problem if rolling a number cube labeled from 1 to 6 and the probability is 12?
The probability of any event is always a number from 0 to 1, inclusive. It can never be 12.
What is the probability of rolling a number less than 4 on a 6-sided number cube labeled 1-6?
3 out of 6, or 50%
What does estimated experimental probability mean please someone answer?
One way of finding the probability is to carry out an experiment repeatedly. Then the estimated experimental probability is the proportion of the total number of repeated trials in which the desired outcome occurs.Suppose, for example you have a loaded die and want to find the probability of rolling a six. You roll it again and again keeping a count of the total number of rolls (n) and the number of rolls which resulted in a six, x. The estimated experimental probability of rolling a six is x/n.
When a number cube is labeled 1 through 6 what is the probability of rolling a 3 write your answer as a fraction in simplest form?
1/6
What happens to theoretical and experimental probability when you increase the number of trials?
When you increase the number of trials of an aleatory experiment, the experimental probability that is based on the number of trials will approach the theoretical probability.
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.
What is the probability of rolling the number 1 when rolling two dice?
The probability is 11/36.
What is the probability of rolling divisors of 6?
when rolling a number cube when rolling a number cube what is the probability of rolling an even number or a divisor of 10? rolling an even number or a divisor of 10?
What is another name for Experimental Probability?
Another name for experimental probability is empirical probability. This is the ratio of the number of outcomes in which a specified event occurs to the total number of trials.
