Plz you roll a number cube twice. what is the probability of rolling a 2 first and then rolling an odd number?

1/36

1/12

1/9

1/4

1/12

Step-by-step explanation:

The probability on an equal dice is 1/6

There is only one 2 on a dice; therefore, the probability of rolling a 2 is 1/6.

There three odd numbers on a dice; therefore, the probability of rolling an odd number is 3/6 = 1/2.

Because the events are dependent on each other (you HAVE to roll a 2 first AND you HAVE to roll an odd number after), multiply them.

1/6 * 3/6 = 1/12

idk

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!
