Question 353919: Assessment 9-2A p. 550#16
16. Four blue socks, four white socks, and four gray socks are mixed in a drawer. You pull out two socks, one at a time, without looking.
a. Draw a tree diagram along with the possible outcomes and the probabilities of each branch.
b. What is the probability of getting a pair of socks of the same color?
c. What is the probability of getting two gray socks?
d. Suppose that, instead of pulling out two socks, you pull out four socks. What is the probability now of getting two socks of the same color? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! b. 3/11
c. 4/12 * 3/11 = 1/11
d. The question is unclear. It doesn't say "exactly" 2 pair. You are bound to get at least 2 socks the same color but you could get 2 pair or three or 4 of a kind.
