At the supermarket, a tasting kiosk invites you to taste a new flavor of biscuits. A marketing study shows that 70% of supermarket customers will taste the biscuits, 5% of customers who have not tasted the biscuits in will buy anyway and 15% of people who have tasted the biscuits will buy them. What proportion of customers will buy biscuits ?
