A firm's annual credit sales are $1.37 million, with 53% of its daily average paid out in purchases. It usually takes the company 31 days to meet its purchasing obligations. This payment pattern has not changed in recent years. However, the firm's commitment to accounts receivable has shifted based on its current annual net income of $28k which meets the 2.28% required return, anticipated by senior management a year earlier. Normally, the firm collects its accounts in 25 days, an average which remains unaffected. Note: Note: The term \"k\" is used to represent thousands (x $1,000). Required: In percentage terms, by how much are the firm's receivables greater than its payables? % Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places (for example: 28.31%). Use a 360-day year.

Determine the following probabilities. a. For n = 4 and ? = 0.15, what is P(X = 0)? b. For n = 11 and ? = 0.30, what is P(X = 10)? c. For n = 11 and ? = 0.50, what is P(X = 9)? d. For n = 2 and ? = 0.81, what is P(X = 1)? a. When n = 4 and ? = 0.15, P(X = 0) = (Round to four decimal places as needed.) b. When n = 11 and ? = 0.30, P(X = 10) = (Round to four decimal places as needed.) c. When n = 11 and ? = 0.50, P(X = 9) = (Round to four decimal places as needed.) d. When n = 2 and ? = 0.81, P(X = 1) = (Round to four decimal places as needed.)
