Question

A company has sales offices in four cities. An analysis of the company's accounts receivables reveals the number of overdue invoices by days, as shown to the right. Assume the invoices are stored and managed from a central database.

What is the probability that a randomly selected invoice from the database is from the City C office? Round it to four decimal places.

Days Overdue Under 30 days 30-60 days 61-90 days Over 90 days City A 121 90 40 25 City B 125 54 32 31 City C City D 219288 71 48 115 52 70

Explanation / Answer

P(Randomly selected invoice is from City C)

= (219 + 71 + 48 + 44) / (121 + 90 + 40 + 25 + 125 + 54 + 32 + 31 + 219 + 71 + 48 + 44 + 288 + 115 + 52 + 70)

= 382/1425

= 0.2681
