ANSWER

[tex]P(A|B)=\frac{1}{3}\approx0.333[/tex]

EXPLANATION

We want to find the probability P(A|B).

This is a conditional probability and its formula is:

[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}[/tex]

where P(A n B) is the probability that the student plays basketball and soccer and P(B) is the probability that the student plays soccer.

We have that:

[tex]P(A\cap B)=\frac{1}{10}[/tex]

and

[tex]P(B)=\frac{3}{10}[/tex]

Therefore, we have that:

[tex]\begin{gathered} P(A|B)=\frac{1}{10}\div\frac{3}{10} \\ P(A|B)=\frac{1}{10}\cdot\frac{10}{3} \\ P(A|B)=\frac{1}{3}\approx0.333 \end{gathered}[/tex]

That is the answer.
