The below three graphs show probability density functions (PDF) of three different random variables Red, Green and Blue. Let P1 be the unknown price of a stock in one year. P1 is a random variable. Let PO=1, so the share price now is $1. This one dollar is a constant, it is not a variable. frequency 0.6 Red/ 0.5 0.4 Blue 0.3 Green 0.2 0.1 -2 -1 0 1 2 variable 3 Which of the below statements is NOT correct? O a. Blue is a stock's gross discrete return (GDR), with a minimum value of zero. O b. Red is log-normally distributed, and the mean is higher than the median. O c. Red is a stock's log gross discrete return (LGDR), with a minimum value of negative one. O d. Blue is a stock's future price (P1), with a minimum value of zero. O e. Green is a stock's continuously compounded return. The below three graphs show probability density functions (PDF) of three different random variables Red, Green and Blue.
