Use the chart below. In a given week, what is the probability that more than 300 CD's sell?

Number of top 10 CDs Sold Each Week
0-100 101-200 201-300 301-400 401-500
0.1 0.15 0.4 0.25 0.1
a) 0.40
b) 0.25
c) 0.75
d) 0.35

Answer 1

To solve this question, I believe what you would do is calculate the total number of CD's sold and then find the number of CD'S sold that are above 300 and then divide the 2 values.


198/496 = 0.399 = 0.40


I believe the solution is a. 0.40.
