Final answer:
The probability that the next person chosen will be in the 50-59 or 60-69 age groups is approximately 25.73%.
Step-by-step explanation:
To find the probability that the next person chosen will be in the 50-59 or 60-69 age groups, we need to calculate the probability of selecting a person from either of these two groups.
The total frequency of the 50-59 and 60-69 age groups is 5410 + 5279 = 10,689. The total frequency of all age groups is 9831 + 7845 + 6869 + 6323 + 5410 + 5279 = 41,557.
Therefore, the probability of selecting a person from the 50-59 or 60-69 age groups is 10,689 / 41,557 ≈ 0.2573, or approximately 25.73%.
