The probability of rolling an odd number on a standard die is 3 in 6, or 1 in 2, or 0.5.
The probability of rolling at least one 2 in fifty rolls of a standard die is 1 - (5/6) 50, or about 0.99989012. This calculation starts by looking at the probability of not rolling a 2, which is 5/6. To repeat that 50 times in a row, you simply raise that to the 50th power, getting 0.000109885. Then you subtract the result from 1 to get the probability of not succeeding in not rolling a 2 in fifty tries. Expressed in normal "odds" notation, this is about (100000 - 11) in 100000, or about 99989 in 100000.
The factors of 10 are the numbers that divide 10 evenly: 1, 2, 5 and 10. To answer your question, you have to figure out what the probability of rolling one of these numbers is on a number cube.
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.
Since there are 6 numbers on a die (1-6), then the probability of rolling a 5 would be 1 out of 6.
5 out of 6 or 83.333%
1 out of 2 or 0.5.
Its 16.667% or 16 1/3%
The probability of rolling an odd number on a standard die is 3 in 6, or 1 in 2, or 0.5.
It is 4/6 = 2/3
1 out of 2
It is a half, one out of 2 or 50:50
1/3
Theoretical probability is the probability of something occurring when the math is done out on paper or 'in theory' such as the chance of rolling a six sided dice and getting a 2 is 1/6. Experimental probability is what actually occurs during an experiment trying to determine the probability of something. If a six sided dice is rolled ten times and the results are as follows 5,2,6,2,5,3,1,4,6,1 then the probability of rolling a 2 is 1/3. The law of large numbers states the more a probability experiment is preformed the closer to the theoretical probability the results will be.
The theoretical probability of not rolling a 2 while the cube rolls 50 times (calling itevent E) is: P(E) = (5/6)50 = 1.09884819... x 10-4 = 0.000109884810... ≈ 0.011%
Assuming a fair die and only one roll, the probability is 1/6.
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.
