Explanation:

Given

See attachment 1 for complete question

Solving (a): The completed square

To complete the square, we simply write out the column header and the row header in to the cell.

For instance:

Column header Be and Row header be will form cell Bbee

See attachment 2 for complete squares

Solving (b):

$(1)\ Black\ hair\ and\ long\ ears.$

This is represented as: BBEE, BBEe, BbEE and BbEe

From the complete cells,

$BBEE = 0$

$BBEe = 0$

$BbEE =0$

$BbEe = 8$

So:

$Total = 0 + 0 + 0 + 8$

$Total = 8$

$(2)\ Black\ hair\ and\ floppy\ ears.$

This is represented as: BBee and Bbee

From the complete cells,

$BBee = 0$

$Bbee = 8$

$Total = 0 + 8$

$Total = 8$

$(3)\ Brown\ hair\ and\ long\ ears.$

This is represented as: bbEe and bbEE

From the complete cells,

$bbEe = 0$

$bbEE = 0$

$Total = 0+0$

$Total = 0$

$(4)\ Brown\ hair\ and\ floppy\ ears.$

This is represented as: bbee

From the complete cells,

$bbee = 0$

$Total = 0$
