Question 851278: Two urns are labeled H and T . The urn labeled H has two red and three blue marbles. The urn labeled T has one red, two white, and one blue marble. A fair coin is flipped. If the coin results in a head, two marbles are selected without replacement from the urn labeled H . Otherwise two marbles are selected without replacement from the urn labeled T .
What is the probability of two red marbles being selected
What is the probability of at least one red marble being selected
Hi,
H marbles: two red and three blue
T marbles: one red, two white, and one blue
If the coin results in a head, two marbles are selected without replacement from the urn labeled H , otherwise...from T
P(2 red) =
P(at least one red) = 1 - P(no reds) = +
