Can you find the cell on the table that corresponds to   'Mini Trucks' and 'B&B motors', what value is in there?

anonymous · Answer

Yes. Its 9.

unklerhaukus · Answer

Good.

Can you find the value in the cell that corresponds to the 'total sales revenue' by 'all four companies'

anonymous · Answer

Umm, no. Do yuo mean the marginal total?

unklerhaukus · Answer

notice that the companies totals go down the table, 

and that the model sales totals go across the table . . .

anonymous · Answer

Alright.

unklerhaukus · Answer

only one cell has the  total sales  by  all companies

anonymous · Answer

is the value to that cell 431?

unklerhaukus · Answer

YEs!

unklerhaukus · Answer

Do you kind-of understand the complicated two-way table now?

anonymous · Answer

Yea. Could you just sort of show me the steps though?

anonymous · Answer

Do i divide now?  9/431?

unklerhaukus · Answer

Now we just need some formula to work out the relative frequency.... 

... exactly!

anonymous · Answer

So my answer would be 0.02?

Thanks alot buddy! You just earned yourself a new fan!

unklerhaukus · Answer

If we analyze the result: 0.02  
ie 2% of money from all car sales, of all companies is B&B mini trucks, 

this sounds very reasonable.
