Of 8 dogs in a kennel, 5 are male and 3 are female. if a trainer randomly chooses two dogs for a walk, what is the probability he will choose two females?

The probability of choosing dogs which are female is  .

Step-by-step explanation:

Total number of dogs = 8

Total number of dogs which are male = 5

Total number of dogs which are female = 3

Probability of choosing one dog which are female out of 8 =

Total number of dogs left in kennel = 7

Total number of dogs left which are female = 2

Probability of choosing second dog which is female out of left dogs =

Hence, probability of choosing two dogs which are female for walk = =

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.
