Elina [12.6K]

Answer:

0.444

Step-by-step explanation:

The objective is to draw the tree diagram and find the probability that the roadrunner took the high road, given that he was caught.

The tree diagram is attached in the image below:

The required probability can be computed as:

P(high\  road  \ | \  caught) = \dfrac{P(high  \ road \  and \  caught)} {P(caught)} \\ \\ P(high \  road  \ |  \ caught) = \dfrac{P(high \  road  \ and  \ caught)}{P(high \  road  \ and  \ caught)+P(low  \ road  \ and  \ caught)}

P(high  \ road \  |  \ caught) =\dfrac{ 0.8*0.01 }{ 0.80*0.01 + 0.20*0.05} \\ \\ P(high \ road  \ | \ caught) = \dfrac{0.008 }{ 0.008 + 0.01} \\ \\

P(high \ road  \ | \ caught) = \dfrac{0.008 }{ 0.018}

\mathbf{P(high \ road  \ | \ caught) = 0.444}
