Use the frequency distribution to the right which shows the number of voters according to age, to find the probability tht a voter chosen at ramdom is in the given sge range not 65 yearls or older.

Age of Voters Frequency
18 to 20 6.4
21 to 24 10.4
25 to 34 20.2
35 to 44 24.3
45 to 64 51.1
65 or older 26.1

Answer 1

0.8116

Explanation:

From the frequency distribution table given

Total Number of voters = 6.4 + 10.4 + 20.2 + 24.3 + 51.1 + 26.1 = 138.5 Million

Number of Voters 65 or Older = 26.1 million

`P($that a voter chosen at random is 65 or older) = (26.1)/(138.5)\\$Therefore:\\P(that a voter chosen at random is NOT 65 or older)$ \\= 1- (26.1)/(138.5)\\\\=0.8116`
