experimental probability
What is the probability that exactly two times head are being tossed?
The answer depends on how many times the coin is tossed. The probability is zero if the coin is tossed only once! Making some assumptions and rewording your question as "If I toss a fair coin twice, what is the probability it comes up heads both times" then the probability of it being heads on any given toss is 0.5, and the probability of it being heads on both tosses is 0.5 x 0.5 = 0.25. If you toss it three times and want to know what the probability of it being heads exactly twice is, then the calculation is more complicated, but it comes out to 0.375.
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 a ratio that shows the total number of times the favorable outcome happened to the total number of times the experiment was done?
The probability of the event occurring.
What is the theoretical probability of rolling a 5 on a number cube if it is rolled 300 times?
The theoretical probability of rolling a 5 on a standard six sided die is one in six. It does not matter how many times you roll it, however, if you roll it 300 times, the theoretical probability is that you would roll a 5 fifty times.
A coin is biased so that the probability a head comes up when it is flipped is 0.6 What is the expected number of heads that comes up when its flipped 10 times?
Multiply the probability by the number of times the experiment was carried out. 0.6x10=6
What is the probability if something comes out 70 percent?
The probability is that it comes out 7 times out of 10 tries, or 70% of the times.
What is prior classical probability?
When you throw a die, there are six possibilities. The probability of a number from 1 to 6 is 1/6. This is classical probability. Compare this with empirical probability. If you throw a die 100 times and obtain 30 sixes, the probability of obtaining a 6 is 30/100 or 0.3. Empirical probabilities change whereas classical probability doesn't.
You throw a die 20 times and it comes up a 5 on 17 out of 20 tosses. What is your best bet for the next roll?
Assuming a fair 6 sided die, there is a 1/6 probability for each number you could choose.
The probability that Julie will make a free throw is 40 percent what is the probability that she will make 4 out of her next 6 free throw shots?
The probability of four out of six shots is the probability of four successes, times the probability of two failures, times the number of permutations of successes and failures: P(four out of six free throws) = 15 * (2/5)4 * (3/5)2 = (15 * 16 * 9) / (625 * 25) = 432 / 3125
What is the probability of getting a multiple of 3 or 4 in throwing a dice?
It depends on how many times you throw it! On a single throw, the answer is 0.5
What is the probability of at least one head?
If you throw a single fair coin multiple times, the probability of getting NO head is:For 1 throw: 1/2 For 2 throws: 1/2 squared = 1/4 For 3 throws: 1/2 cubed = 1/8 etc. The probability of getting AT LEAST ONE head is the complement; for example, for 3 throws, it would be 1 minus 1/8.
What is the probability that a dye never comes up an even number when it is ruled six times?
P(not even) = P(odd) = 3/6=1/3 When rolled 6 times, the probability of an even number not showing up is (1/3)^6 = 1/729.
If you toss a coin 1000 times and find that it comes up head 532 times what is the probability of getting a tail?
The probability is still 50%
With two dice what is the probability to throw a 2 three times in a row?
(1/36)3
The probability of rolling 5 40 times is 12 What is the probability of rolling 5 500 times?
Probability is a number between 0 and 1. The probability of an event cannot be 12.
How many times must you throw two standard dice to be sure you get the same sum at least twice?
The probability of gettting a particular sum on a standard set of dice depends on which sum you are seeking. For example, the sums of 2 and 12 have a probability of 1 in 36, or about 0.0278; while the sum of 7 has a probability of 6 in 36, or 1 in 6, or about 0.167.Specifically answering the question; it is not possible to guarantee a particular outcome in a random throw, or in a series of random throws, of the dice. You can only talk about probability. Let's take the worst case of trying to throw a 2 or a 12. Even of you throw the dice 100 times, the probability is only 0.0278100, or about 2.34 x 10-156 that you will not throw the 2 or 12; so, the probability is extremely good that you will throw a 2 or 12 in 100 throws, but it is not guaranteed. That's the thing about probability.
