Tyrone Shoelaces has invested a huge amount of money into the stock market and doesn't trust just anyone to give him buying and selling information. Before he will buy a certain stock, he must get input from three sources. His first source is Pain Webster, a famous stock broker. His second source is Meg A. Cash, a self-made millionaire in the stock market, and his third source is Madame LaZora, world famous psychic. After several months of receiving advice from all three, he has come to the following conclusions: Buy if Pain and Meg both say yes and the psychic says no. Buy if the psychic says yes. Don't buy otherwise. Use the following: x: Pain (1: saying yes; 0: saying no) y: Meg (1: saying yes; 0: saying no) z: LaZora (1: saying yes; 0: saying no) F: Purchase function (1: buy; 0: do not buy) The minimized Boolean function to implement the logic telling Tyrone when to buy : F(x, y,z)
