Answer:
Step-by-step explanation:
We have been given a table to voters and their ages. We are asked to find the probability that a voter is younger than 45.
Voting age Voters
17-29 9
30-44 8
45-64 32
65+ 15
We can see from our given table that age of 17 (9+8) voters is between 17 to 44 years.
To find the probability that a voter is younger than 45, we will divide 17 by total number of voters.
Therefore, the probability that a voter is younger than 45 is 0.27.
