Mr. and Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 0.38. If they have four children, what is the probability that at most two of their four children will have that trait? Round your answer to the nearest thousandth.

the answer is c hope it

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
