Question 631089: Suppose E and F are independent events and P(E)= 1/3 and P(F)= 1/4. Find P intersection F. Find P(E U F). Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Suppose E and F are independent events and P(E)= 1/3 and P(F)= 1/4. Find P intersection F. Find P(E U F).
-----
P(EUF) = P(E)+P(F) - P(E and F)
----
P(E U F) = 1/3 + 1/4 - (1/3)(1/4)
---
P(E U F) = (7/12) - 1/12 = 1/2
