What are the probability that: A customer is both female and purchases food? A female customer purshases food? A customer purchasing food is female?
------
With the given data, develop a contingency table.
---------------
Let fe be female ; Let fo be purchases food
P(fe and fo) = 0.35
P(fo | fe) = 35/40 = 0.875
P(fe | fo) = 35/50 = 0.70
