A jar contains dimes and quarters. Twenty percent of the coins in the jar are dimes. A number generator simulates randomly selecting 10 coins from the jar. The number generator is used 12 times and the number of dimes in each trial is shown in the dot plot.

Which description is correct about the number generator being fair or not?

The question is not complete, so i have attached the complete question.

Option C is the correct option:

The number generator is fair. It shows that 20% of the coins selected are dimes most of the time.

Step-by-step explanation:

From the question, we are told that 20% of the coins are dimes, and that 10 coins are selected.

Thus, the expected number of dimes is; 0.20 × 10 = 2

From the dot plot shown in the attached image, we can see that 2 has the most frequent appearance.

Hence, we can say that the number generator is fair because It shows that 20% of the coins selected are dimes most of the time.
