Answer:

Relative Frequency Method

Step-by-step explanation:

If I carry out an experiment involving 25 throws of a coin and I obtain 13 Heads(H), the Relative Frequency of obtaining Heads will be 13/25.

Now if I intend to find out approximately how many Heads will

occur in 300 throws, I simply use the result or experimentation data that I have.

This is done below:

Relative Frequency of Obtaining a Head= 13/25 =0.52

Number of Heads obtained in 300 throws

= Relative Frequency X Number of Trials

=0.52 X 300

=156

This is an example of how relative frequency method works.
