If an insurance company pays $5000 for complete loss, $1500 in case of a loss of $2000 and more and nothing in case the loss is less that $2000. It obviously pays nothing in case of no loss. If the probability of the first 3 events are 0.02,0.10 and 0.3 , find what should the company charge in order to make a profit of $50 from each customer ?
