Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

What is the theoretical probability of rolling a 10 after rolling the dice 50 times?
I'll answer your question literally before guessing at what you really meant.
The probability of rolling a 10 is not influenced by what was done before, assuming perfect dice, of course. So the fact they were rolled 50 times before makes no difference, the probability remains 1 in 12.
But maybe you meant, "What is the theoretical possibility of rolling a 10 at least once in 50 throws?"
To figure that out, you work out the opposite and then take 1 minus that.
You ask yourself, "What is the probability of NOT rolling 10 in 50 throws?"
Now that's easy. The odds for any one throw is 33/36 (there are 3 ways to throw 10: 4&6, 5&5, 6&4). So the odds of no 10 in 2 throws is (33/36)x(33/36) and for 50 throws, it is (33/36) to the 50th power.
That is an extremely small number, so the opposite (chance of at least one roll or 10) is almost a sure thing (1 - (33/36)50).

What are the odds of eight matching dice out of ten die in one roll?
The odds of one die being any number is 1 in 1. The odds of any of the next seven dice being the same as the first die is 1 in 6. The odds of the last two being different than the first die is 5 in 6.
The dice are unrelated to each other, and it does not matter in what order they are thrown, so the odds of eight matching dice out of ten dice is (1 in 1)1 (1 in 6)7 (5 in 6)2, or 25 in 10,077,696.
If a spinner having 2 colors red and blue is spun twice what is the possible outcome?
it will land on red once and it will land on blue once aswell
What is the probability that at least one tail appears when tossed 6 times?
you have 63 chances out of 64. i once witnessed a coin being tossed seven times and giving up 7 consecutive heads. we never tried it an eighth time, 7 heads and you had to go to the bar.
If you roll two dice at once What is the possibility of rolling a 7?
There are 21 possible results. Of the 21, there are 3 ways it can end up to have the sum of 7 (1 and 6, 2 and 5, 3 and 4). 3/21*100%=14.3% (14.3% chance to get 7)
If there repetition is allowed (like 4 for dice A and 5 for dice B + 5 for dice A and 4 for dice B is 2 counts), there will be 36 possible results. There will also be 6 possible ways to get two numbers to have a sum of 7. 6/36=16.7% (16.7% chance to get 7)
There is also another situation where the meaning of the question is to roll a 7 from another dice (example n-sided dice). Chances of getting a 7 from two dices is 2/n (if n is less than 7 excluding 7, it is unsolvable)
What is the chance that a second baby will be a girl?
At present the global probability of a new-born child being a girl is approx 0.48 and so this is a simple answer to the question. However, the gender of a child depends on the ages and genes of the parents and that will be different for each set of parents.
What is the difference between natural infinite numbers and real infinite numbers?
A natural number is a counting number, such as 1, 2, 3. There are also known as whole numbers and integers. They can be infinitely large.
A real number is a number, possibly a natural number, but more possibly not, because there are an infinite number of real numbers that lie between any two natural numbers, such as 1, 1.1, 1.11, 1.111, 111112, etc, ad infinitum. Real numbers can also be infinitely large.
How many ways can you read 4 books from a shelf containing 12 books?
12 choices for the first book, 11 choices for the second, 10 choices for the third, and 9 choices for the fourth. 12 x 11 x 10 x 9 = 11880.
What is the probability of failing 75 times on a 2 percent chance of success?
If the probability of succeeding is 2%, then the probability of failing is 98%. The probability, then, of failing 75 times is 98%75, which is 22%.
