A disk drive manufacturer sells storage devices with capacities of one terabyte, 500 gigabytes, and 100 gigabytes with probabilities 0.5, 0.3, and 0.2, respectively. The revenues associated with the sales of the storage devices in that year are estimated to be $50 million, $25 million, and $10 million, respectively. Let X denote the estimated revenue of storage devices during that year. Determine the probability mass function of X.

Step-by-step explanation:

From the given information;

Revenue connected to 0.5 probability = 50 million

Revenue connected to 0.3 probability = 25 million

Revenue connected to 0.2 probability = 10 million

Suppose X is the variable that represents the revenue of storage devices in that year, Then: the probability mass function;

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

pretty sure 750 each month!
