Annual profit (P) is the product of total annual sales (S) and profit per unit sold (X); that is, Pequals=Xtimes•S. It is desired to know the probability distribution of the random variable P when X and S have the following assumed probability mass functions (X and S are independent). What are the mean, variance, and standard deviation of the probability distribution for annual profit, P?

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
