There are 24 students in a science class. Mr. Sato has given 9 pairs of students their 3 magnets. How many more magnets does Mr. Sato need some that each pair of students has exactly 3 magnets?

AS there are 24 students in the science class, there are 242=12 pair of students. Therefore number of pairs of students yet to be given magnets is 12−9=3 . For them he needs 3×3=9 magnets.

Step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
