What is the probability of the player matching exactly 3 numbers from a 10 number lottery (0...9) w/o repetition, given the conditions:
- player and lottery pick 6 numbers;
- player always has a repeated number;
- lottery always has a repeated number.
for example:
123455
123455
Here there's many matches of 3. Because it's a match of 6/6 it means that there are C(6,3)=20 matches of 3... I think
Note. Legit choice:
123455
112345
It also means the player matched 4 numbers while picking only 3, which means C(4,3) ways to match a 3 number... match
