If a coin is flipped 20 times and a head comes up 7 times, what is the relative frequency of a head coming up?
Tju [1.3M]
Relative frequency is the absolute frequency (i.e. the number of times of the wanted result) divided by the total  number of events.

In this case you have to calculate: the number of heads that came up divided by the number of times the coin was flipped.

Number of times the coin was flipped: 20
Numbef of times head came up: 7

Relative frequency: 7 / 20 = 0.35, which is the option B.
