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:

%40

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
