if there are 54 in total, and 32 are women, that means 22 are men, we get this by subtracting 32 from 54 (54-32).
then if 18 of the 41 are male, who are right handed, subtract 18 from 41 (41-18) to get 23. that means there are 23 right handed women.
then we do 32-23 to get 9, this is how many left handed women there are.
then we do 22-18 which is 4. there are 4 left handed males
