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}

Bond [772]

Answer:

You download 32 rock songs.

Step-by-step explanation:

The ratio 5 : 4 can also be written as the fraction 5/4.

The ratio pop songs, 40 : rock songs, r can be written as the fraction 40/r

Set an equation:

40/r = 5/4

Cross Multiply:

5r = 160

Divide 5 from both sides:

r = 32

There you have it, the amount of rock songs downloaded! Hopefully this helps!
