wel

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.

Nastasia [14]

Answer:

53/10, 5 9/25 ; 5.81 ; 5.818

53/10 = 5.3

5 9/25 = 5.36

So we have that the solution is:

53/10, 5 9/25 ; 5.81 ; 5.818
