A local high school offers five sports for male students: basketball, soccer, football, hockey, and volleyball. Students are allowed to play as many sports as they like. Let V represent a student who plays volleyball and F represent a student who plays football. Given a randomly selected student, P(V) = 0.9, P(F) = 0.6 and P(V and F) = 0.5. What is the probability that a randomly selected student plays volley ball, given that they play football, P(V|F)? Justify your answer
