An urn contains 14 pens in a jar. There are 6 black pens and 8 blue pens. You draw two pens from the urn but replace the first pen before drawing the second. Find the probability that you will get 2 blue pens, i.e., P (the first pen is blue and the second pen is blue)?

19. An urn contains 30 balls identical in every respect except color. There are 15 red balls, 7 green balls, and 8 blue balls. You draw two balls from the urn (without replacing the first ball before drawing the second). Find the probability that the first ball is green and the second is blue. Express your answer as a decimal.

You draw two balls from the urn but do not replace the first ball before drawing the second. An urn contains 12 balls identical in every respect except color. There are 3 red balls, 7 green balls, and 2 blue balls. Find the probability that the first ball is red and the second is green. Write your answer as a decimal to the nearest thousandths place (0.XXX).

1. A jar contains 3 black and 2 white marbles. We continue to draw marbles one at a time until two black marbles are drawn. If a white marble is drawn, the outcome is recorded, and the marble is put back in the jar before drawing the next marble. What is the probability that we will get exactly two black marbles in at most three tries? Do this problem using a tree diagram! (2 marks)

A jar contains 6 white beads and 3 black beads. Beads are chosen randomly from the jar one at a time until the third time a black bead turns up. a. Suppose that each bead is replaced before the next is chosen. How many beads should you expect to be chosen in the course of the experiment? [5] b. Suppose that if a bead is white, it is not replaced before the next...

Assume there is a jar with a green, blue, and red balls in it. Draw two balls from the jar, with replacement (i.e., you put the |first ball back in the jar before drawing the second). You would like to determine the number of green balls drawn from the jar. What is the random variable in this experiment? What is the sample space for this random variable? Which outcomes are associated with the different values the random variable can take?
