A raffle jar contains 10 purple tickets, 7 blue tickets, and 4 red tickets. What is the probability of randomly selecting a blue ticket, and without replacing it, then randomly selecting a purple ticket? A. 2/21 B. 1/10 C. 1 / 7 D. 1/6

You have 7 blue tickets and 21 total.

So the odds of pulling a blue ticket is 7

21

If you replace the ticket, the total number of tickets changes, so the total is 20 tickets.

The odds of pulling a purple ticket is 10

20

So the odds that you pull a blue, replace it, then pull a purple is:

7 * 10 = 70 = 1

21 20 420 6

so your answer is 1/6 or D
