Two flower seeds are randomly selected from a package that contains 8 seeds for red flowers and 13 seeds for white flowers
(a) What is the probability that both seeds will result in red flowers?
P(2 red) = 8C2/21C2 = 0.133
-----------------------------------------
(b) What is the probability that one of each color is selected?
# of red/white pairs = 8*13 = 104
# of random pairs: 21C2 = 210
P(red/white pair) = 104/210 = 0.495
------------------------------------------
(c) What is the probability that both seeds are for white flowers?
# of white/white pairs 13C2
# of random pairs: 21C2
P(2 white) = 13C2/21C2 = 0.371
