In mathematics, a combination is a way of selecting items from a collection, such that (unlike permutations) the order of selection does not matter. In smaller cases it is possible to count the number of combinations. For example, given three fruits, say an apple, an orange and a pear, there are three combinations of two that can be drawn from this set: an apple and a pear; an apple and an orange; or a pear and an orange. More formally, a k-combination of a set S is a subset of k distinct elements of S. If the set has n elements, the number of k-combinations is equal to the binomial coefficient
which can be written using factorials as whenever , and which is zero when . The set of all k-combinations of a set S is sometimes denoted by .
Combinations refer to the combination of n things taken k at a time without repetition. To refer to combinations in which repetition is allowed, the terms k-selection,k-multiset, or k-combination with repetition are often used. If, in the above example, it was possible to have two of any one kind of fruit there would be 3 more 2-selections: one with two apples, one with two oranges, and one with two pears.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Probability and statistics are two related but separate academic disciplines. Statistical analysis often uses probability distributions, and the two topics are often studied together. However, probability theory contains much that is mostly of mathematical interest and not directly relevant to statistics. Moreover, many topics in statistics are independent of probability theory.

Imaginext-Toys presents: By request we have combined 6 Batman and Robin episodes.
The street is cold, the dawn is gray
My heart says no but my head says stay
My work is finished, or so I've been told
You can't part the three of us, once we got a hold
I forgot my name
I took a shot on the chin
I'm rearranging my game
Tell by the shape I'm in
In the line of fire, you know what to say
They gave us no choices, just one shade of gray
My legs keep moving, don't seem to stray
But I know each step we take, they're one step away
I found the secret, the key to the vault
We walked in darkness, kept hittin' the walls
I took the time, to feel for the door
I found the secret, the key to it all
I got the Nouveauree
And dragged it home to bed
I traded you for me
I took it all and said
I find my own fun, sometimes for free
I got to pay it to come looking for me
Walking on Gucci, wearin' Yves Saint Laurent
Barely stay on, 'cause I'm so God damn gaunt
I found the secret, the key to the vault
We walked in darkness, kept hittin' the walls
I took the time, to feel for the door
