emmy chooses a marble at random from a bag. there are 2 red marbles and 1 blue marble. which tree diagram represents the sample space of this event?

Answer

Answer:

The fourth tree - diagram (with two R's and one B) represents the sample space.

Explanation:

Step1: Identify total marbles

There are 2 red (R) and 1 blue (B) marbles.

Step2: Analyze sample - space requirements

The sample space should show 2 red and 1 blue outcome possibilities. The first tree - diagram has two B's only, the second has three R's only, the third has two B's and one R. The fourth has two R's and one B which matches the marbles in the bag.
