**Mutually Exclusive Events**

definition: two events that cannot occur at the same time

example: picking a number that is even and picking a number that is odd

if A and B are two mutually exclusive events then P(A or B) = P(A) + P(B)

**Mutually Inclusive Events**

definition: two events that can occur at the same time, "overlapping"

example: picking a number that is even and picking a number that is less than 10

if A and B are two mutually inclusive events then P(A or B) = P(A) + P(B) - P(A and B)
