Answer 2

Step-by-step 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`
