The research department of a board game company surveyed Some shoppers at a local mall. The team asked shoppers how often they read the newspaper, among other questions. Then
the team played a memory card game with the shoppers. They recorded how many cards
each shopper remembered.
The probability that a shopper reads the newspaper 1-2 times a week is 0.9, the probability
that a shopper remembered 4-6 cards is 0.2, and the probability that a shopper reads the
newspaper 1-2 times a week and remembered 4-6 cards is 0.1.
What is the probability that a randomly chosen shopper reads the newspaper 1-2 times a
week or remembered 4-6 cards?
