Respuesta :

Answer:

[tex]0.07[/tex]

Step-by-step explanation:

FORMULA :

[tex]p\left( A|B\right) =\frac{p\left( A\cap B\right) }{p\left( B\right) }[/tex]

……………………………

then

[tex]p\left( \text{drive to school} |sophomore\right) =\frac{p\left( \text{drive to school} \cap \text{sophomore} \right) }{p\left( \text{sophomore} \right) }[/tex]

                                [tex]= \frac{2}{2+25+3}[/tex]

                                [tex]=\frac{2}{30}[/tex]

                                [tex]=\frac{1}{15}[/tex]

                                [tex]=0.066666666667[/tex]
