Erin has four shirts (white, blue, red, black) and two pairs of pants (blue and black). she randomly chooses a shirt and a pair of pants. what is the probability that they are the same color?

The probability is:

Step-by-step explanation:

It is given that:

Erin has four shirts (white, blue, red, black)

and two pairs of pants (blue and black).

Let W denote white

B' denote Blue

R denote red

and B denote Black color.

This means that the pair that can be made with the help of the four shirts and 2 pants are:

{WB',WB,B'B',B'B,RB',RB,BB',BB}

Total number of combinations possible=8.

The number of combinations that or same color are: 2

( since BB,B'B' are the two combinations)

Hence,the probability that they are the same color is:

Hence, the probability is:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
