Consider an investor who randomly selects two stocks out of a group of five stocks. Assume that the stocks vary in terms of their investment grade, 1 being the best investment, 2 being the second best, 3 being the third best, and so on, for 4 and 5. Assume that these rankings are unknown to the investor.
A: FInd the probability that the investor selects the best and one of the two poorest stocks (1 and 4, or 1 and 5).
B: Find the probability that the investor selects at least one of the two highest best (1,2) stocks.
