F Note: For this type of question in the midterm exam, you are required to show all the intermediate steps on a piece of paper. Failure to do so will result in a grade of zero even if your answer is correct. (x+y) (x+y)'(x + y) Oxty x'(x+y) Jey has invested a huge amount of money into 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 Suresh. Ja famous stockbroker. His second source is Sasi, a self-made millionaire in the stock market, and his third source is Prem, a world-famous psychic. After several months of receiving advice from all three, he has come to the following conclusions: a. Buy if Suresh and Sasi both say Yes and the psychic says No. b. Buy if the psychic says Yes. c. Don't buy otherwise. Construct a truth table and find the minimized Boolean function to implement the logic telling Jey when to buy using K-map.
