#### How many marbles are drawn without replacement from the jar?

Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles. a) Draw the tree diagram for the experiment. A bag contains 5 blue balls and 4 red balls. A ball is picked and not replaced.

**How do you sample two marbles in a box?**

Consider a box containing 3 red, 2 blue, and 1 yellow marble. If we sample two marbles, we can do this either: ● without replacement of the first before the second is drawn. The highlighted branch represents a blue marble with the first draw and a red marble with the second draw.

**What are the odds of getting a non yellow marble?**

like Sal mentioned a 3/8th chance That is roughly 37.5\% chance of picking a yellow marble leaving a 62.5\% chance of picking a non yellow marble (those add up to 100\%)
