Answer:
The answer is B the relative frequency is 0.2 it is likely that most ducks are yellow
Step-by-step explanation:
Sophia randomly picks up a duck and then replaces it. She repeats this process 100 times.The relative frequency is 0.3. It is likely that most ducks are yellow.
How to find the relative frequency?
Relative frequency is the ratio of the considered sub-groups count to the total count. (so its frequency of the considered subgroup relative to the total frequency).
Sophia randomly picks up a duck and then replaces it. She repeats this process 100 times.
The table shows the results of her experiment.
Duck Color Times Picked
red 30
green 20
yellow 40
blue 10
Total number of ducks = 100
The relative frequency of choosing a red duck
= 30 / 100
= 0.3
Thus, The relative frequency is 0.3. It is likely that most ducks are yellow.
