Question 15 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. Not yet saved a Marked out of 4.00 frequency P Flag question 0,6 Red 0.5 0.4 0.3 Blue Green 0.2 0.1 -2 -1 0 1 2 2 variable 3 Which of the below statements is NOT correct? O a. Red is a stock's gross discrete return (GDR), with a minimum value of negative one. O b. Green is normally distributed with the same mean and median. O c. Green is the log gross discrete return (LGDR). O d. Red is log-normally distributed, and the mean is higher than the median. O e. Blue is a stock's future price (P1), with a minimum value of zero.
