Help with shaping data

I'm attaching a pbix file where everything is setup for help. Basically, I need a slicer to group data and split them by a column. The data has 3 columns:

Shopper

Product
IsPurchase

A user needs to select a product from a slicer, and I need a table to show products and count of shoppers that have IsPurchase=1 for the selected product in the slicer, but IsPurchase=0 for the product in the row. 

If you open the pbix file and look at the data, you will see better what I need help with

Here is the file: PBIX

THANKS!
