After a campaign to encourage students to take precautions against skin cancer, in a certain high school class consisting of  27 girls and  30 boys, it is observed that  20 girls and  17 boys take precautions as measured by a survey to elicit how often they wear sunscreen, sunglasses and hats for protection against the sun.

What is the probability that a student picked at random takes precautions against skin cancer (by wearing sunscreen, sunglasses and a hat), given that the student is a boy?
