Hi,
for 2nd questions, it asks 'the probability that the citizen both voted in the last election and was age 25 to 34 is". Isn't the answer 10%?

Unlike first question, here it is not mentioned about selecting from the pool of eligible voters. so we should look at whole population right?
Percentage of population who are 25 to 34 and voted is = 16.1% * 58% (approx) = 9.3% close to 10. Did I miss something here?

Should we consider the first condition to apply for both questions?
The sentence: "If a citizen... was selected" applies to both the parts of the question. The question phrases also include the term citizen and it refers back to the initial starting phrase as no other citizen is mentioned to which it can attributed to. Had sentence correction still been a part of GMAT this would've been clearer.

Can someone please explain both the questions?

In Nation X, all citizens aged 18 or older are eligible to vote and all citizens under age 18 are not. The left graph shows the percentage of citizens of Nation X who fell within various age ranges at the time of the last election. For the same age ranges during that election, the right graph shows the voter turnout—the percentage of eligible voters who voted.

Select from each drop-down menu the option that creates the most accurate statement based on the information provided.

If a citizen of Nation X who was eligible to vote at the time of the last election was selected at random, the probability that the citizen was age 25 to 34 is, to the nearest percent, and the probability that the citizen both voted in the last election and was age 25 to 34 is, to the nearest percent,

Eligible citizens = everyone except Under 18.

So eligible percentage = 100 - 24.2 ≈ 75

Age 25 to 34 citizens ≈ 16

First probability:

16/75 ≈ 21%

For the second probability, use the 25 to 34 turnout rate, about 60%.

So:

16/75 * 0.6 ≈ 12%

Answers:
first dropdown: 21%
second dropdown: 12%
