Heh, i just did this one the other day.

We basically need to pick two points that satisfy x, and two points that satisfy y.

Since there are 10 possible values for x: we do 10*9 and since there are 11 possible values for y we do 11*10.


Multiply those all together, and you get 11*9*10*10 = 99*100 = 9900

C.

If you need more explanation, i'm happy to help.

Hi I would like to know why did multiply 10*9 and 11*10.

I know that there are 10 values of X and 11 values of Y. But just cant understand the product part.

Thanks
