Subscribers to a store’s coupon distribution list are each emailed a randomly generated discount code which consists of 4 letters followed by 3 digits (some customers may getthe same code). Most codes are for 25% off online shopping on Cyber Monday, but customers whose codes consist of all different letters and 3 digits in increasing order(e.g. MATH014) get 50% off instead.

What is the probability that a code will consist of all different letters and 3 digits in increasing order?

In a group of 10 subscribers, what is the probability that at least two subscribers will get 50% off?

In a group of 1000 subscribers, what is the expected value and standarddeviation for the number of subscribers who will get 50% off?

A few weeks ago you crated a program which randomly generated a wind-speed, and the output told us what category of cyclone it was. Your solution may have looked like this: import random def main():     wind_speed = random.randint(0, 255)     if wind_speed in range(0, 118):         message = str(wind_speed) + "\n It is not yet a cyclone"     elif wind_speed in range(119, 153):         message = str(wind_speed) + "\n It is a Category 1 cyclone"     elif wind_speed in...

Answer: True or False for each statement. (1) For a discount bond, the coupon rate must be greater than the current rate. (2) Under CAPM, idiosyncratic risk plays an important role in an asset's required rate of return. (3) If CAPM does not hold, then the idiosyncratic risk plays a significant role in the total risk of a well-diversified portfolio. (4) The realized return on an equity (i.e., stock) investment can never be negative. (5) The beta on the market...

#5) At maturity, each of the following zero coupon bonds (pure discount bonds) will be worth $1,000. For each bond, fill in the missing quantity in the following table. Assume semi-annual compounding. (Round present value factor calculations to 5 decimal places, e.g. 1.25124 and final answers to 2 decimal places, e.g. 15.25 or 15.25%.) Price Maturity (years) Yield to maturity A $441 10 ??? % B $409 ??? 5 % C ??? 15 13 %
