Probability of each event green marbles blue marbles total of marbles p1 15 25 125 40 125 second event assumes a blue or green was chosen for first event so there is one fewer marble on top and also one fewer marble in the total number of marbles. Based on this dotplot which of the following is the best estimate of the probability of drawing 3 or. If we got a blue marble before then the chance of a blue marble. The dotplot below shows the number of red marbles out of 15 drawn in 200 computer simulations of this random process.

The marbles should be positioned in a crossed and spaced 3inches from each other. Say you want to figure out the probability of drawing a white marble of which there are 11 out of the total pot of marbles which contains 20. The chance is 2 in 5.
