The probability of the coin landing heads-up is 0.3 experimentally and 0.5 theoretically .
a) The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.
Thus the experimental probability of the coin landing heads up is
=9/30
= 0.3
b) Theoretical probability is the likelihood that an event will happen based on pure mathematics. The formula to calculate the theoretical probability of event A happening is
Thus the Theoretical probability of the coin landing heads up is
= 1/2
=0.5
