1/6, because there are six sides, so it would have to be 1 chance out of those six. :)

95 percent is, statistically, 2 sigma.

This is a combinations question. The answer is C(10,8), the number of combinations of 10 things taken 8 at a time, which also equals the number of combinations of 10 things taken 2 at a time. You can imagine why these are the same: choosing 8 questions to answer out of ten is the same thing as not choosing 2 questions to answer out of ten. C(10,2) = (10*9)/(2*1) = 45. There are 45 different choices the student can make of which eight questions to answer.

4 possible kings out of 52 cards.

1/13

I think of it this way. Take it as two unique 6-sided dice, then you have 36 possible outcomes (6 times 6). Two of these outcomes will add to equal 3 (2 & 1, and 1 & 2), so there are 34 [36-2] outcomes which don't sum to 3. The probability is 34/36 or about 94.44 percent chance.

If you're asking what the probability you don't roll AT LEAST three is, the only roll on two normal dice less than three is two, and there's only one way to roll it: 1,1. So the probability of not getting AT LEAST three on two fair dice is 1/36.

1/4? ...

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).

An ace of spades is one of the 52 playing cards in a standard set, with a single pip and the nominal value of 1, with the spades suit.

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.

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.

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%.

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.

just go to the question like this and it will tell you
