Also the monthly profit earned by Guindy unit is normally distributed with mean 16.5 (in thousands) and standard deviation 1.5 (in thousands). Further the Taramani unit earns monthly profit which is normally distributed with mean 17 (in thousands) and standard deviation 2 (in thousands). What is the probability that the monthly profit of Guindy unit exceeds that of the Taramani unit? Hint: Difference of two normally distributed random variable is also normal.
