As customers were entering the local supermarket, they were surveyed to determine if they had subscribed to one of the streaming services (NetFlix, Stan, Apple TV, Amazon Prime, Binge, Etc) and how they would classify their income level (high, medium and low). The results are summarised below:

Income Level	Has subscribed	Hasnotsubscribed
High	320	80
Medium	192	708
Low	48	252

What is the probability for the following:

a: a person has low income? (1 mark)

b: a person has a high level of income and has subscribed? (2 marks)

c: given the person has a medium-income, they had not subscribed to a streaming service? (2 marks)
