Question

We have a set of 40,000 data points representing customers of a TV streaming service.  Each data point includes binary variables indicating whether or not the customer has watched each TV show that the streaming service provides.

The support of {Walking Dead} is 6000 customers, or 0.1500

The support of {Archer} is 3000 customers, or 0.0750

The support of {Walking Dead, Archer} is 900 customers, or 0.0225
