Total number of socks = 12 + 6 + 9 + 3 + 10 = 40
Number of grey socks = 3
We'll multiply the probabilities to find the answer in this case.
\(\Large \color{MidnightBlue}{\Rightarrow {3 \over 40} * {3 \over 40} }\)
\(\Large \color{MidnightBlue}{\Rightarrow {9 \over 1600} }\)

i got half of that guess im always close to figuring it out but never get there thx

That only works if he put the sock back in the draw otherwise its
3/40 * 2/39; because he chooses a grey sock first which changes the odds
