the music department of a department store sold 12 just CDs last month jazz sells during the month we have 2% of the music departments total sales suppose that the store sells 14 sets jazz CDs during the next month and the percent of the sales from the jazz CDs is still 2% what is the total number of the CDs that the store will sell

a. 600 CDs

b. 700 CDs

Step-by-step explanation:

a. Let us assume the number of CDs sold during the month be x

Number of CDs sold = 12

Given Percentage = 2%

So, the equation be

2% of x = 12

x = 600

So, the number of CDs sold during the month is 600

b. Now the number of CDs sold during the next month be y

Number of CDs sold = 14

Given Percentage = 2%

2% of y = 14

y = 700

So, the number of CDs sold during the next month is 700

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
