Question

What is the difference between relative frequency and experimental probability? The formulas are the same

Answer 1

Does anyone know?

Answer 2

relative frequency assumes you are repeating the experiment

Answer 3

so for example if you flip a coin 100 times and get 46 heads and 54 tails, the relative frequency of heads is \(\frac{46}{100}=.46\)
of course the probability you toss heads is \(\frac{1}{2}\)

Answer 4

Yes. But how do I know when to use experimental probability then?

Answer 5

Answer 6

The term relative frequency is used for the ratio of the observed frequency of some outcome and the total frequency of the random experiment. Suppose a random experiment is repeated N times and some outcomes is observed f times, then the ratio f/N is called the relative frequency of the outcome which has been observed f times.

Experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials.

Answer 7

So experimental probability isn't exact? Is that the difference?

Answer 8

@nitz

Answer 9

but probabiity is never exact.......it is just chance of occcurence of an event

Answer 10

I still don't get what the difference is between relative frequency and experimental probability and how to work out when to use it

Answer 11

Anyone?
