Iran surveyed a random sample of students in her school district, and she found these statistics:
\begin{aligned} &P(\text{rides bike to school})=0.14 &P(\text{has crossing guard})=0.48 &P(\text{rides bike and crossing guard})=0.12 \end{aligned}
P(rides bike to school)=0.14
P(has crossing guard)=0.48
P(rides bike and crossing guard)=0.12
Find the probability that a student rides a bike to school, given that the student's school has a crossing guard.
