[Video] Q9: The table above shows the number of registered voters in 2012, in thousands, in four geographic regions and five age groups. based on the table, if a registered voter who was 18 to 44 years old in 2012 is chosen at random, which of the following is closest to the probability that the registered voter was from the midwest region?

Explanation for Question 9 From the Math (Calc) Section on the Official Sat Practice Test 4

Now hearing question number nine, we're looking at our table, 2 right? And it's got voters registered in 2012 and four geographic ranges 3 right here, and then some age groups as well. 4 It says based on the table, if a registered voter who was 18 to 5 24 years old in 2012 was chosen at random. 6 So that sentence really shows us what age group are we focusing on only 7 these. So if anyone from that age group was chosen at random notice 8 that there's a total of about 15,000 there, 9 which of the following is closest to the probability that they will be from 10 Midwest. So essentially the whole that we're looking at here is, 11 um, voters that are 18 to 24 years old. 12 That really gives us our total and our probability, 13 which we put in our denominator. Right? 14 So we're looking at a total of about 14,766 people, 15 but we're only interested in picking someone from the Midwest. 16 That's our part or our numerator, which is 3,453. 17 So now we just need to put that into our calculator, 18 right? Three, four or five, three divided by 14, 7, 6, 6. 19 And that gives us about 0.23, 20 which is closest here to answer choice B.
