Abag contains 4 blue marbles, 2 black marbles, and 3 red marbles. if a marble is randomly drawn from the bag, what is probability that it is not black?

dont trust me im no expert these losers made me fail a test bro this sucks

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
