An efficiency expert is doing a study of a certain fast food restaurant. She observes that a particularly clumsy waiter drops 30% of all the hamburgers that he serves. What is the probability that he will drop exactly four of the next ten?

Hello,

I don't know the words used for that binominal exercice.

Step-by-step explanation:

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
