A laundry bag contains 7 brown socks and 2 black socks. Find the probability of picking a brown sock first,
followed by a black sock, if the first sock is NOT returned to the bag before the second sock is picked.

Answer

7/9 chance to pick a brown sock first and 1/4 chance to get a black sock after

Step-by-step explanation:

there are 9 total socks and 7 are brown so you will have a 7/9 chance to get a brown sock

then if you do get a brown the total number of socks will be 8 in the bag so then you have a 2/8 chance which can be simplified to 1/4
