The sole likelihood of overlap anywhere between six and you can 20 anyone above is the case: V – S – C or V – C – S, both in situation, V ‘s the basic.=> Brand new overlap = 20 + 6 – twenty four = 2
The latest Q claims that choose as well as was to bring their liking step one-2-step three smart, very everyone has voted and you can considering the taste where order..essentially there’s absolutely no one who has not voted.. _________________

In the a marketing survey, 60 everyone was expected to rank around three flavors regarding ice-cream, chocolates, vanilla, and strawberry, under control of their liking
Total sixty someone need review c, v, s step 3/5 *60= 36 somebody score: CSV or SCV1/10*60 = six someone rank: VCS otherwise VSC otherwise SVC1/3*sixty = 20 someone rating: VCS or VSC or CVS
As we know there exists just 6 combinations for C, V, S rating – CSV, SCV, VCS, VSC, SVC CVS. Full people soon add up to getting 60. Yet not, VCS and VSC is overlapped in-group dos and you may step three
Full some body = 60 Class 1+Classification dos + Group step 3 = 36+6+20 = 62The merely more than lap was 2, and this equals to the count getting VCS + VSC
It discover it’s sometime extended which is the reason why I would not pick it up regarding mock exam (so it matter took me
