A jar of marbles contains 9 red marbles, 5 blue marbles, 3 pink marbles, 2 yellow
marbles, and 1 purple marble. A marble
will be drawn from the bag and replaced
50 times. What is a reasonable
prediction for the number a times a pink
or purple marble will be drawn?

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
