Answer 1

Given in the question:

a.) Joey's sock drawer is unorganized and contains 5 black dress socks, 7 black ankle socks,

4 brown dress socks, and 2 brown ankle socks.

To be able to get the probability that Joey chooses a sock at random that is brown or is a dress sock, we will be using this formula:

$\text{ Probability = }\frac{No.\text{ specific socks}}{\text{Total no. of socks}}$$\text{Probability}_{Brown\text{ and Dress}}=\frac{No.\text{ of Brown Socks}}{Total\text{ no. of socks}}\text{ x }\frac{No.\text{ of Dress Socks}}{\text{Total no. of socks}}$$\text{Total no. of socks = 5 + 7 + 4 + 2 = 18 socks }$$undefined$
