if we select AAA then we have to give 3 more varieties which can either be BB & C or CC & B similarly for BBB and CCC hence 3x2 =6 correct me if I am wrong🤗

sorry I replied wrong ques no it cannot be 6 coz it will be repeated AAABBB or AAACCC similarly for BBBAAA or BBBCCC CCCAAA or CCCBBB look there are only 3 cases AB BC AC
Can you explain me the question where 12 things of 3 different varities are considered to be distributed among 2 persons P and Q? Why dont we consider the case of person Q and simply calculate the cases of person P. I am a little confused.
sir i am uncomfortable with your soln of ex 2
