A math class consists of 25 students, 14 female and 11 male. Two students are selected at random to participate in a probability experiment. Compute the probability that no males are selected.

In the die the total no. of students are 25

We know that,

∴ P(E) = Number of favourable outcome / Number of all possible outcome

Here we have to find the probability of the event of finding the no. of males.

⇛ P(E) = 14 / 25 (Answer)

And we are done !!

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.

the answer is 62.8 cubic units
