Answer:

Step-by-step explanation:
Given
P(A or B)= P(B)-P(A and B)
P(A)=1/3
P(A and B)=1/8
P(A or B)= 3/4
Required
Find P(B)
To find P(B), all we need to do is to substitute values of P(A or B) and P(A and B) in the given equation.
This goes thus;
P(A or B) = P(B) - P(A and B) becomes

Make P(B) the subject of formula

Take L.C.M

Add fractions

From the workings above, the value of P(B) using the given equation is 
3- 3x - 36×36 =
3 - 3x - 1296 =
3 - 1296 -3x=
-1293 - 3x
Answer:
576 People
Solving:
If the total number of people that downloaded songs from the site ( 100% ) equals "x," and 60% of "x" plus 384 equals "x," 384 must be 40% of "x" to add up to 100% ( the percentage of people "x" represents ).
384 / 40% = 960 = x
x = 0.6 ( x ) + 384
960 = 0.6 ( 960 ) + 384
960 * 60% = 576 people
