Jordan uses a 20% off coupon when she buys a camera that originally cost $100.00 how much money does jordan save and what is the new cost of the camera after she uses the coupon?

P = 0.622

Step-by-step explanation:

Since 8/10 own an Android, the probability on the first selection is 8/10.

Since the second selection is done without replacement (meaning the first selection is removed from the available choices) the probability of getting a student who owns an Android is 7/9  (we lose one possible Andriod, and one total person from the selection pool).

To solve this we multiply the probabilities together..

(8/10)(7/9) = 56/90  which equals 0.622222 as a decimal, but the question wants it rounded to 3 decimals, so the final answer is 0.622
