So you use x = 2.
x-2 = 0
x+7=9
so (0,9) (x,y)
18 tablespoons 12 fits into 72 6 times and 6x3 is 18
5 beads each a different color
so every time she picks a bead she has a 1/5 probability of picking a certain color
she does it 3 times so you get:
1/5 x 1/5 x 1/5 = 1/125 probability of picking those colors
It lies first line have a nice day
