2. Apply Exactly 62% of the students in your school are under 17 years old.
In addition, 4% of the students are over 18. What is the probability that a
student chosen at random is under 17 or over 18?
You have a drawer with five pairs of white socks, three pairs of black socks,
and one pair of red socks. You choose one pair of socks at random each morning,
starting on Monday. You do not put the socks you choose back in the drawer.
