When I get my tax refund this year , there’s a 30% chance I will buy a wide screen tv, a 20% chance I’ll buy a blue ray player and a 10% chance I’ll buy both. What’s the chance I buy neither?

3women sell hats at a craft fair weekly. the money they make at the fair is split into categories. 9% goes to pay taxes. $55 goes to pay rent for the space they sell in. the rest is split between the women. if the group make $706 at the fair, how much does each women get paid once the money is divided
