Answer: 0.55
Step-by-step 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 :-
\(\frac{\text{favorable outcomes}}{\text{Total outcomes}}=\frac{11}{20}=0.55\)
Hence, The relative frequency of a head coming up =0.55
