You have a new product. You have to decide on which seeling price ($3 or $4) to charge. The demand (units in million) for each price and probability distribution is as follows:
probability of dd (units)			$3		$4
probability of dd (units)
0.1			160 m units		60 m units
0.2			200		170
0.3			280		260
0.4			400		330
computed the expected demand in units compute the standard deviation of demand at $3 and 4$ and finally compute the coefficient of variation = standard deviation / mean which price should you charge and why?
