Consider three urns, one colored red, one white, and one blue. The red urn contains 1 red and 4blue balls; the white urn contains 3 white balls, 2 red balls, and 2 blue balls; the blue urn contains4 white balls, 3 red balls, and 2 blue balls. At the initial stage, a ball is randomly selected fromthe red urn and then returned to that urn. At every subsequent stage, a ball is randomly selectedfrom the urn whose color is the same as that of the ball previously selected and is then returnedto that urn. (1) In the long run, what proportion of the selected balls are red

i think its a and d

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
