Conditional probability: find the probability that a particular location is an urban one, GIVEN THAT it is operating at a loss.
Informally, the "given that" means the denominator of the probability fraction is only the number of locations that are operating at a loss: 132
The numerator of the probability fraction is the number of locations that are operating at a loss and are also rural: 38
The probability is then 38/132, which is approximately 28.8%.
ANSWER: 28.8%
Formally, the conditional probability is
P(operating at a loss AND urban) (38/243)
---------------------------------- = ---------- = 38/132
P(operating at a loss) (132/243)
