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 a 3 or 5 on a die?
a 2 out of 6 probability
What is the probability of rolling a 2 on a die and then re-rolling the die and getting an even number?
The probability of rolling a 2 is 1 in 6. The probability of rolling an even number is 3 in 6. The probability of doing both, on two rolls, is 3 in 36, or 1 in 12.
When rolling one die 12 times what is the probability of rolling a 2?
The probability of rolling at least one 2 when rolling a die 12 times is about 0.8878. Simply raise the probability of not rolling a 2 (5 in 6, or about 0.8333) to the 12th power, getting about 0.1122, and subtract from 1.
Rolling an even number on a die?
Probability of rolling an even number on a die is 1/2.
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 probability of rolling an odd number with a dice?
The probability for a normal die is 1/2.
What is the probability of rolling a die and rolling a 2?
1 out of 6 if it's a perfect cube.
What is the probabilities of rolling a 2 with two dice?
The probability of rolling a sum of 2 is 1/36 The probability of rolling the value 2 on one die or the other (or both) is 11/36
If you alternate between flipping a coin and rolling a die what is the probability of rolling a 2 before flipping a heads?
The probability of rolling a 2 on a die before flipping a heads on a coin is 1 in 12. The probability of rolling a 2 is 1 in 6. The probability of flipping heads is 1 in 2. Since these are sequentially unrelated events, you simply multiply the probabilities together.
What is the probability of rolling an even prime number with one roll of a die?
Since there is only one even prime, 2, the probability of rolling a 2 with one die is 1 in 6.
What is the theoretical probability of rolling a multiple of 2 on a die?
1 out of 2 or 0.5.
