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?

A

0.1

B

0.25

C

0.4

D

0.75

Text Solution

Verified by Experts

The correct Answer is:
B
According to the table, in 2012 there was a total of 14,766 + 47,896 = 62,662 registered voters between 18 and 44 years old, and 3,453 + 11,237 = 14,690 of them were from the Midwest region. Therefore, the probability that a randomly chosen registered voter who was between 18 and 44 years old in 2012 was from Midwest region is `(14,690)/( 62,662) ~~ 0.234`. Of the given choices, 0.25 is closest to this value.
Choices A, C, and D are incorrect and may be the result of errors in selecting the correct proportion or in calculating the correct value.
