Question 1112689
A company sells pencils that are painted blue or green. A package of three pencils from this company has a random mix of these pencils. A person used a simulation to determine the probability that exactly 2 of the 3 pencils in a package are painted green. A coin was used for the simulation, where the side labeled with a “B” represented blue, and the side labeled with a “G” represented green. The results of 30 trials of the simulation are shown below. 
GBG	BBG	BGG	BBB	GBB	GGG
BBB	BGB	BBG	BGG	BGG	BBG
GBB	GGG	BBG	BBB	BGB	GGB
BBG	GGB	BBG	GGG	GGG	GBB
GGB	BBB	GGB	BBG	GGG	BGG
Based on the simulation, what is the probability that exactly 2 of the 3 pencils in a package are painted green? 
-----
Ans:: Count the number of triples that have exactly 2 G's.
That is the numerator of the correct answer.
--------
A.9/30
B.14/30
C.12/30
D.16/30
