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.

If tom throws in four coins to a fountain what is the chance that only one coin is heads?
your chances are 1 in 16.
What is the probibility of choosing a jack from a standard deck of 52 playing cards?
4 in 52, or 1 in 13, or about 0.0769
Yes.
Well technically we don't really know if noble six is dead or not, but it is assumed that he is dead. But to answer your question, (spoiler alert) if you go back and beat the campan on legendary you have to do an extra mission and that is to stay alive but it is impossible so don't try it. Any way he get over taken by some elites and dies. if you want to see what happens here is the link.

What is the history behind normal distribution?
The discovery of the Normal distribution is sometimes attributed to de Moivre, who in 1738 published his results on the coefficients in the binomial expansion of (a + b)n. He calculated results for the mean and spread of the binomial expansion. Although it is now possible to relate his theorem to the Normal approximation of the Binomial Distribution, de Moivre himself, was unable to do so because he was unaware of the the concept of a probability density function.
In 1809, while developing the theory concerning the method of least squares he concluded that the only law which worked was to use the normal law of errors.
A year later Marquis de Laplace proved the Central Limit Theorem. According to this, no matter what the underlying density functions, the means of repeated samples from a population tended towards a nomal distribution. It was also he who calculated the integral of exp(-t2)dt as being sqrt(pi) which allowed the function to be normalised.

What is the probability that you will win if you buy one of 200 raffle tickets to win a television?
The odds are 1 in 200. The probability of winning is 0.005.
You cannot, because you have no information on the variance or standard error.
When you take one cracker out of that bag, eat it, and reach into the bag
for another one, the probability that the next animal will match the first one
is
9/29 = about 31% .
A standard deviation of 0 implies all of the observations are equal. That is, there is no variation in the data.
No. 21 is not a factor of 182. The prime factorization of 182 is 21 x 71 x 131.

In a jar with 17 blue marbles and 43 black marbles when I grab 7 of them how many will be blue?
The total marbles are 60, your mathematical expectation of getting a single blue marble in one try is therefore 17/60. If you grab 7 random marbles, the mathematical expectation is 7 times 17/60. This is the expectation, in an actual experiment you will get more or less than that, but it should be fairly close to the calculated value. (Note that the mathematical expectation in this case isn't even an integer.)
