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.
Report Abuse. A negative number minus a negative number is always positive because while adding or subtracting a negative number, we keep it in brackets. If there is a minus before the brackets, when we remove the brackets,minus and minus multiply to become positive.For Ex. 12-(-5) = 12 -x- 5 = 12+ 5 = 17. negative number minus a negative number is always positive because while adding or subtracting a negative number, we keep it in brackets.
