Well, a pair of students means two. if there are 24 students then there are: 24/2 = 12 pairs of students.
9 pairs already got their magnets. 12 - 9 = 3 pairs still need magnets.
each pair gets 3 magnets. So he needs 3*3 = 9 more magnets
The probability that the card is not yellow is 
<em><u>Solution:</u></em>
<em><u>The probability of an event is given as:</u></em>

From given,
A box is filled with 8 blue cards, 8 yellow cards, and 2 green cards
Total number of possible outcomes = 8 + 8 + 2 = 18
Favorable outcome = card is not yellow
Favorable outcome = card is blue or green = 8 + 2 = 10
Therefore,

Thus the probability that the card is not yellow is 5/9
Answer:
675
Step-by-step explanation:
If the price is 20 % off, then we will pay 100-20 = 80 percent of the original price
Let x be the original price
x* 80% = 540
Change to decimal form
x * .80 = 540
Divide each side by .80
.80x / .80 = 540/.80
x =675
The original price is 675
Answer:
