A
2
Q
What is the formula when you are trying to solve for something when it say “or” or a synonym to that
A
P(A)+ P(B)- P(A and B)
- and = intersection
3
Q
Mutually exclusive formula
A
P(A or B)= P(A) + P(B)
4
Q
when to use the Given Formula
- and the formula
A
- when the equation says Given you solve for it
-P(A Given B)= P(A n B)/P(B) - second subject goes into denominator
5
Q
product test for independence
A
- only use when checking for independence
- P(A) x P(B)= P(A n B)
6
Q
whats another way to find independence that isn’t the product test
A
P(A given B)= P(A)
- for this one first subject goes into the =
