Homework Statement
Given that [tex]P(T) = P(U) = 0[/tex] then show that [tex]P(T \cup U) = 0[/tex]
Given that [tex]P(T) = P(U) = 1[/tex] then show that [tex]P(T \cap U) = 1[/tex]
Homework Equations
I am told that I need to use the following equations.
(1) [tex]P(T \cup U) = P(T) + P(U)[/tex] if [tex]P(T \cap U) = 0[/tex]
(2) [tex]P(T \cup U) = P(T) + P(U) - P(T \cup U)[/tex]
The Attempt at a Solution
My Solution for question one.
Since We know that [tex]P(T) = P(U) = 0[/tex] then by using equation
We get that [tex]P(T \cup U) = P(T) + P(U) = 0 + 0 = 0[/tex]
My Solution for question two.
Here I have a feeling that I need to use equation two, but how do I deduce
[tex]P(T \cup U)[/tex] ??
