Conjecture
The conclusion formed by using inductive reasoning, since
it may or may not be correct.
Inductive reasoning
Is the process of reaching a general conclusion by
examining specific examples.
Example of inductive reasoning

simple interest
I = Prt
I - interest earned in one year, usually
P - principal, the amount borrowed
r - the percent of the interest being charged (rate)
t - the time in years

Counting Principle
If there is a decision to be made about how many ways
something can happen and that decision can be broken
down into several tasks or choices and you know how
many ways there are to make each choice (n ways to
make first choice, n ways
