x and y are real numbers
Find the values of x and y that will minimize 2x-y^2.

Re: True or False easies
Thomas has 16 cookies, where 14 are sugar and 2 are chocolate chip. He wants to share the cookies with his 4 friends, Romeo, Jones, Lee, and Kim. He puts the cookies in a bag and his friends select 4 cookies. What is the probability that 2 friends get 1 chocolate chip cookie?
