The below three graphs show probability density functions (PDF) of three different random varlables Red, Green and Blue. Let P1 be the unknown price ofaacone year, P1 is a random varlable. Let PO-1, so the share price now is $1. This one dollar is a constant, It is not a variable.frequency2,6Red/ 0.90.40.3BlueGreen,0.20.1-2variable3Which of the below statements is NOT correct?Oa Blue is a stock's future price (P1), with a minimum value of zero.O b. Red is a stock's net discrete return (NDR), with a minimum value of negative one.Oc. Blue is a stock's log gross discrete return (LGDR), with a minimum value of zero.O d. Green is normally distributed with the same mean and median.O e. Red is log-normally distributed, and the mean is higher than the median.2.

The price of a stock can never be negative so the statement a. is valid. Returns from stock can be…

What does the memoryless property refer to? An event cannot occur if it has already occured within a recent specified time period. The distribution of the time until an event does not depend on how much time has already passed. The occurrence of an event is independent of the number of times that event has already occurred. None of the above.
