Type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar. zoe is shopping for a new car and has to make some decisions. the model she's chosen comes in two versions, hybrid and electric. for the exterior, she can choose red, blue, or green. for the interior, she can choose fabric, leather, or vinyl. if zoe randomly chooses from the options, the probability that zoe picks a blue hybrid car with an interior that is not leather is . if zoe randomly chooses from the options, the probability of zoe picking an electric car in a color other than blue is . reset next

Step-by-step explanation:

a) p(blue & hybrid & not-leather) = p(blue)×p(hybrid)×p(not leather)

  = (1/3)×(1/2)×(2/3) = 1/9

__

b) p(electric & not-blue) = p(electric)×p(not blue) = (1/2)(2/3) = 1/3

Among a given set of choices, the probability of any one of them is 1 divided by the number of choices. The probability of that the choice is not one of those is the probability that it is, subtracted from 1.

Example: there are 3 colors, so p(green) = 1/3; p(not-green) = 1 -1/3 = 2/3.

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
