Let P(E)=0.25 and P(F)=0.45
1. Find P(E and F) if P(E or F)=0.6
P(E and F) = P(E)+P(F)-P(E or F)
P(E and F) = 0.25+0.45-0.6 = 0.1
--------------------------------------------------
2. Find P(E and F) if E and F are mutually exclusive.
P(E and F) = 0
---------------------------------------------------
3. Find P(Fc)
P(F') = 1-0.45 = 0.55
====================================================
