Question

If a coin is flipped 20 times and a head comes up 11 times, what is the relative frequency of a head coming up?

Answer 1

Answer: 0.55

Explanation:

Given: The total number of times coin is flipped =20

⇒ Total outcomes =20

The number of times heads comes up= 11

⇒ Favorable outcomes = 11

Now, the relative frequency of a head coming up is given by :-

`\frac{\text{favorable outcomes}}{\text{Total outcomes}}=(11)/(20)=0.55`

Hence, The relative frequency of a head coming up =0.55
