Answer 1

It just need an extra sheet/table to execute..

try :

A1 = a,b,c
A2 = b,c
A3 = c,b,a
A4 = c,a
A5 = b
B1 = ss
B2 = ss
B3 = dd
B4 = dd
B5 = ss
D1 = a
E1 = b
F1 = c
C7 = ss
C8 = dd

D2 =IF(FIND(D$1,$A2,1)>0,1,"") drag until F6

D7 =COUNTIFS($B$2:$B$6,$C7,D$2:D$6,1) drag until F8

D7:F8 will be your desired results. Happy trying.
