Johnny did a survey and discovered that 5 out of 32 students walk to school. If 3 students are randomly selected from Johnny's school, without replacement, what is the probability that all 3 students walk to school? 1⁄4,960 = 0.06%

1⁄496 = 0.2%

15⁄8,192 = 0.18%

3⁄16,384 = 0.02%

3⁄7,440 = 0.04%

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.
