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.

How many different ways can you arrange the numbers 1 to16?

If all 16 numbers show up in each arrangement, then they can be arranged in

20,922,789,890,000 different ways.

(That number is rounded to the nearest ten thousand, so it's accurate to within

one ten-millionth of 1 percent.)

What is the probability of getting an a from Alabama?

There are four a's in ALABAMA. The probability of choosing an a from a random draw of those seven letters is 4 in 7, or about 0.5714.

If you are talking about getting a grade of A from a school in Alabama, that is entirely up to you and to how well you apply yourself.

How many outcomes are there for one toss of the octohedron and one toss of the dodecahedron?

There are 96 possible outcomes. A dodecahedron has 12 sides, so it has 12 possible outcomes. An octohedron has 8 sides. So for each of the 12 outcomes on the dodecahedron, the octahedron has 8 possible outcomes, hence you multiply 12 x 8 = 96.

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.

How does noble six die?

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.
