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.
The product of a negative and a positive is negative. (-1) x (-2) = 2 (-3) x (4) = (-12) ------------------------------ In Division Dividing a negative by a negative yields a positive number. Dividing a negative by a positive, or a positive by a negative, yields a negative number.
