A bucket contains 5 green tennis balls, 2 yellow tennis balls, 6 red tennis balls, and 8 blue tennis balls. Tony removes 4 tennis balls, without replacement, from the bucket. What is the probability that Tony removes 1 yellow, 1 green, and 2 blue tennis balls?

A. 0.25, 0.33, 0.25, 7/20

B. 0.29, 0.13, 0.25, 0.33

C. 0.13, 7/23, 0.25, 5/24

D. 3/24, 8/24, 0.29, 8/24

answer is b

Step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
