Erin has four shirts (white, blue, red, black) and two pairs of pants (blue and black). she randomly chooses a shirt and a pair of pants. what is the probability that they are the same color?

The probability is:

Step-by-step explanation:

It is given that:

Erin has four shirts (white, blue, red, black)

and two pairs of pants (blue and black).

Let W denote white

B' denote Blue

R denote red

and B denote Black color.

This means that the pair that can be made with the help of the four shirts and 2 pants are:

{WB',WB,B'B',B'B,RB',RB,BB',BB}

Total number of combinations possible=8.

The number of combinations that or same color are: 2

( since BB,B'B' are the two combinations)

Hence,the probability that they are the same color is:

Hence, the probability is:

depends on how many days you are talking about

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
