Big cure and little cure are both pharmaceutical companies. big cure presently has a potential "blockbuster" drug before the food and drug administration (fda) waiting for approval. if approved, big cure's blockbuster drug will produce $1 billion in net income for big cure. little cure has ten separate, less important drugs before the fda waiting for approval. if approved, each of little cure's drugs would produce $50 million in net income. the probability of the fda approving a drug is 50%. what is the expected payoff for little cure's ten drugs?
