Joey's sock drawer is unorganized and contains 3 black dress socks, 5 black ankle socks, 7 brown dress socks, and 6 brown ankle socks. what is the probability that joey will blindly reach into his sock drawer and pull out a sock that is brown or a dress sock?

i got 1/3 by doing: 13/21+10/21-16/21=7/21 which is 1/3 simplified. is this correct?

16/21 is the answer so you are not correct

Step-by-step explanation: There are 21 socks total. And we want a dress sock or brown so there are 7 brown dress socks,3 blacks dress socks and 6 brown ankle socks. 7+6+3=16

so in conclusion the answer is 16/21

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
