I’m having difficulty doing a homework problem involving Bayes’ rule.
The formula to be used is:
P(A|B) = P(A)*P(B\A) / (P(Ai)*P(B|Ai) (The formula can be better seen at the bottom of thispage)
My problem lies in the fact that after many tries, I do not know my variables’ values from this set of probabilities:
P(F|Small) = .3 P(U|Small) = .7
P(F|Medium) = .6 P(U|Medium) = .4
P(F|Large) = .8 P(U|Large) = .2
With F = Favorable and U = Unfavorable
Just can’t figure out what values to fill in the formula to get the answers which are :
If someone could show the steps to get one of the answers I’m sure I can figure out how to do the rest. Thanks in advance!
