You can put this solution on YOUR website! 1) Indicate the formula for the following conditions.
P(X | Y) = [P(X and Y)/P(y)
----------------------------------------
2) 2, 3, 6, 8, . . . is an example of an infinite alternating series.
True or False
False
---------------------
3) 3, 9, 12, 15 . . . is an example of an infinite arithmetic series.
True or False
It is an infinite aritmetic sequence.
------------------------
4) Type the general term for the following sequence.
3, 9, 27, 81, 243, . . .
a(n) = 3^n
________
5) Type the general term for the following sequence.
3/4, 6/5, 9/6, 12/7, 15/8...
a(n) = (3n)/(n+3)
-----------------
6) Identify the following series as arithmetic, geometric, both, or neither.
2x + 2x^2 + 2x^3 + 2x^4 + . . . + 2x^n + . . . geometric_
7) Identify the following series as arithmetic, geometric, both, or neither.

8) Identify the following series as arithmetic, geometric, both, or neither.
-1 + 3 + 1 + 3 -1 + . . . neither____________
9) Evaluate the following expression.
P(3,3) = 3*2*1 = 6______
10) Evaluate the following expression.
C(3,3) = 1______
11) Evaluate the following expression.
C(6,3) = (6^5*4)/(1*2*3) = 20_______
