Questions

Three cards are placed in a hat—one card is blue on both

sides, one is red on both sides, and one has a blue side and a

red side. A card is drawn at random from the hat and you see

that one side is blue. What’s the probability that the other

side is blue?

A. 1/3

B. 1/2

C. 2/3

D. 3/4

Further Exploration – Problem Sets

The historical probabilities that a birth event results in

identical or fraternal twins are about 1/300 and 1/125,

respectively. Given that Elvis Presley had a twin brother

who died at birth, what is the probability that Elvis was an

identical twin? Assume that boys are as likely to be born,

in general, as girls. (Hint: This is the same probability that

a birth event results in identical twin boys given that we

know it results in twin boys.)
