Answer:A) 24 waysB) 4 waysStep-by-step explanation:a) permutation occurrs when order of choices matters.N = 4P3 = 4!/(4-3)! = 4!/1!N = 24 waysb) combination occurs when order of choices doesn't matter.N = 4C3 = 4!/3!(4-3)! = 4!/3!(1!)N = 4 ways

8100 is 5400*1.5, so 180*1.5 is 270 winners
The standard equation of a circle:
(h, k) - center
r - radius
We have:
(2, -8) → h = 2, k = -8
r = 9
Substitute:
The fraction for that is 1/2
