Lyrics:
Now usually I don't do this, but uh
I'm gonna break it down for you about finite math
Now I'm not trying to sound smart
Finite math is really hard
With twelve baseball cards
How many ways can batting start?
Thats why I'm all up in this class
Wanna do more than pass
Applications for these maths
Got me studying the facts
(If I) Throw you twelve Red Sox
You can pick the line up
Run Papelbon first fo sho'
The others I don't know
But lets give it a go
This is called permutation
The trend sweeps Red Sox Nation
If a list is ordered then you use this golden equation
P eleven pick 8 [P(11,8)]
Factorial this way
Who'd have thought so many line-ups
Are possible each game?
Red Sox Red Sox Red Sox Red
Red Sox Red
Now another thing Ive learned
Is the standard normal curve
Bet you'll be surprised by
How many purposes it serves
First I thought what you're thinkin'
How often will 0 be the mean?
Wait till I show you how to mix in
The standard deviation
So give me the square root
Of that variance to
Find your sigma fo' sho'
Subtract mu from b so
You can divide and go
To Z(area)
Find Probability
In Finite Math
Chalk Boardin' it up
Figuring Monty Hall
Picking blue and red balls
With TI-83s
We pluggin' it out
