Is the experimental or theoretical probability higher for the coin landing heads side up

Question

A coin was flipped 30 times.

Side  Frequency  
Heads  16  
Tails  14  

Is the experimental or theoretical probability higher for the coin landing heads side up

kropot72 · Answer

The following ratio estimates the probability of the coin landing heads side up:

number of occurrences of heads side up
----------------------------------
            number of trials
The accuracy of the probability estimate increases as the number of trials increases. If the coin is fair, then after hundreds of trials the probability of heads will be very close to 1/2.

so theoretical ?

kropot72 · Answer

For a fair coin the theoretical probability of heads or tails is 1/2 which is less than 16/30. So the experimental estimate of the probability of heads is higher than the theoretical probability.
