Question

A box contains three marbles: one red, one green, and one blue. Consider an exper-iment that consists of taking one marble from the box then replacing it in the boxand drawing a second marble from the box. What is the sample space? If, at alltimes, each marble in the box is equally likely to be selected, what is the probabilityof each point in the sample space?

Answer 1

Answer:

Sample space =

{ ( RR, RG, RB, GG, GR, GB, BB, BR, BG) }

i.e 9 sample points in the sample space.

If each outcome is equally likely, then the probability = 1/9
