A concession stand at a movie theater offers soda and popcorn for sale. A survey shows that that 50% of moviegoers purchase a soda, 45% of moviegoers purchase popcorn, and 25% of the moviegoers purchase both soda and popcorn. We define the following events for a randomly chosen moviegoer: A:purchases a soda B: purchases popcorn For each of the events described below, provide an expression using events A and B; and compute their respective probabilities. (a) A randomly chosen moviegoer purchases a soda but not popcorn. (1 (b) A randomly chosen moviegoer purchases a soda or popcorn. (c) A randomly chosen moviegoer does not purchase anything.
