Creating Dummy Variables using Excel

Hi all,

I'm having an excel sheet with 10 existing columns (each column represent one owner).

The values 1 and 2 in the cells stand for Male or Female.

Now I have to create dummy variables,
where Dummy1=1 when the group consist of 2 people; 1 male and 1 female
where Dummy2=1 when the group consist of 2 people with equal gender
where Dummy3=1 when the group consist of 3 or more people (disregard gender)

Could anyone please help me with a formula for this?
My aim is to create a new column for each dummy, where value is 0 or 1.

Thanks in advance!
