Continental Congress. Franklin returned to Philadelphia in 1775. There he served as a delegate to the Continental Congress, where he was instrumental in drafting the Declaration of Independence and the Articles of Confederation to form a new union.
In its simplest form (when r is an integer), the negative binomial distribution models the number of failures x before a specified number of successes is reached in a series of independent, identical trials. Its parameters are the probability of success in a single trial, p, and the number of successes, r. A special case of the negative binomial distribution, when r = 1, is the geometric distribution, which models the number of failures before the first success. More generally, r can take on non-integer values.
A negative number is a number below zero. It can be an integer or a decimal and is written with a minus sign (-) in front of it, like this: -3. You can get an idea of what a negative number is with a number line, like this one: ---|---|---|---|---|---|---|---|---|---|---|---|---|---|- ... -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 You can see from this number line that you can continue counting down when you get to zero.
