A bag contains 8 red marbles, 9 white marbles, and 9 blue marbles. You draw 3 marbles out at random, without replacement. Probability that no two colors are the same?.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
