This is a Bayes Theorem Problem

P(oil | negative test) P(negative test)= P(negative test | oil) P(oil)

P(oil | negative test) = P(negative test | oil) P(oil) / P(negative test)

P(oil | negative test) =P(negative test | oil) P(oil) / ( P(negative test | oil) P(oil) + P(negative test | no oil) P(no oil) )

We're given the prior probability of oil, P(oil)=.45, so P(no oil)=.55

We given P(negative test | no oil) = 0.80, so P(negative test | oil) = .20

$P(\textrm{oil} | \textrm{negative test}) = \dfrac{ .20(.45) }{.20(.45) + .80(.55)} = 0.1698$
