Write down 3 cases for the situation -> case 1 is no oldest man or women. Case 2 is one oldest man, no oldest women. Case 3 is oldest women but no oldest man.
7 men with one oldest, means there are 6 non-oldest. 6 women with one oldest means there are 5 non-oldest women.

Thanks alot! Appreciate the help
No prob. Didn't know H3 math has this topic. I thought it's under the usual H2 math topic, called permutations and combinations. But they learn this on yr 2 though, under statistics.
I learn this in poly haha
