It would likely be somewhere around 3000, but almost certainly not exactly that number. The Law of Large Numbers in probability says that when something is done over and over again (like asking 5000 people), the actual results will be very close to (but not necessarily equal to) the expected result.

for every 5 people, 3 prefer TVs
for every 1 person, 3/5 prefer TVs
so, for every 5000 people, (3/5)*5000 prefer TVs = 3000
hence, 3000 people prefer a TV Set

3000 people would prefer a tevevison set. Just set it up as a proportion and cross multiply.

three out of five people is too small of a sample population to derive a definative answer unless you are in a perfect world. in that case, if you were in a perfect world, it would be 3000 people.
