Suppose you have a bag that contains 1 black, 4 white, and 5 striped marbles. You select one marble, replace it, and then select another. Find the probability that you will select two striped marbles in a row.

There are 10 marbles, of which 5 are striped.

The probability of getting a striped marble on the first draw is 5/10.

Since you replace the marble, the probability of also getting a striped marble on the second draw is 5/10,

The probability of getting two striped marbles in a row is 5/10 x 5/10.
