the total number of permutation possible.

2491

Calculate first the total number of permutation possible.

You select two socks so that will be:

14â‹…13=182

Now you must first select a blue sock then a black sock:

You can only pick 8

possible blue socks You can only pick 6

possible black socks

which means that this permutation (blue→black)

have 8â‹…6=48

possibilities for each different blue and black sock.

express in fraction:

48182=2491

in case your curious, all possibilities have the following odds:

(blue→blue)=56182=2891

(black→black)=30182=1591

(black→blue)=48182=2491

24+24+15+2891=9191
