A die is rolled and the results are 1, 2, 1, 4, 5, 6, 1, 3, 6, 6, 5, 2, 3.

True or false: The experimental probability of rolling a 2 is close to the theoretical probability.

please help<3

We have A = 2 copies of "2" showing up out of B = 13 rolls total

A/B = 2/13 = 0.1538 is the experimental probability of rolling a 2

Compare this with 1/6 which is the theoretical probability of rolling a 2 (since there is one side labeled "2" out of 6 sides total)

1/6 = 0.167 approximately

Comparing 0.1538 with 0.167 is fairly close

or you could argue that 2/13 is close to 2/12 = 1/6

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
