You have flipped the bottle cap 20 times (13 up + 7 down)

Therefore,

The experimental probability of the bottle cap landing down = 7/20.

The experimental probability of the bottle cap landing up = 13/20

It is as simple as that!

To further explain

The experimental probability is the result of the experiment - you ignore all "theoretical" probabilities.

For instance in an experiment you toss a fair coin 100 times. You record each outcome and find that heads appeared 55 times and tails 45 times. What is the "experimental" probability of a head occurring on the next toss? What is the "theoretical" probability of getting a head on the next toss?

Answers

"Experimental" probability = 55/100 = 55%. Only the result of the experiment counts, ignore theory.

"Theoretical" probability = 50%. Heads and tails for a fair coin have equal probability of occurring and you ignore what has gone on in the experiment beforehand. Each coin has a 50% chance of coming down heads on each and every toss.

in case you have a device as an occasion the place marbles can fall down via many pegs the place the marble can deflect good or left ast each and every peg it is going to be possible to calculate the place the marbles will land (theoretical) or the device could be build and the effect desperate by easily attempting out (experimental). you may the two build an easily variety or devise a mathematical variety.
