Please help me with the following question.

f Given independent random variables with means and standard deviations as shown, find the mean and standard deviation of the random variable 3X-Y. X Y Mean 95 88 OA. P3x-y 197,03x-y = 20.25 OB. Pax-Y 197,03x-y = 57.43 OC. Pax-y=7,03x-y = 40.00 OD. Pax-Y 197,03x-y = 40.00 OE. Max-y=373, 0x-y = 57.43 OA. a=0.462 OB. o=0.663 OC. a=0.961 OD. a=0.680 OE. o=0.440 SD 19 7 Solve. In a box of 15 batteries, 7 are dead. You choose two batteries at random from the box. Let the random variable X be the number of good batteries you get. Find the standard deviation of of X
