Question 488449: I would be very delighted if you could help with my probability question,
In a business's survey of 500 customers ,of their 240,000 costomers, how many unsatisfied customers should the business expect for their to be?
___________________________________
Pleased Satisfied Unsatisfied
-----------------------------------
126 339 35
___________________________________
What is the probability of the customer being unsatisfied?
I already knopw that I have to put the numbe of unsatisfid customers over the number of customers surveyed total. I found out that that would be a fraction of 35/500 and when simplified is 7/100. (I divided by 5).
Although I do not know how to set 7/100 up as a proportion.

Proportion:
Although I do not know how to set 7/100 up as a proportion.
x/240,000 = 7/100
----
x = (7/100)240,000
x = 16,800
