Question

answer the following question based on the data in the table.
24
select the correct answer.
what is the probability that a person with an iron deficiency is 20 years or older?
a. 0.23
b. 0.34
c. 0.60
d. 0.78
(the table is about iron deficiency and age, with rows: yes, no, total; columns: less than 20 years, 20 - 30 years, above 30 years, total. the data: for yes row: less than 20 years 41, 20 - 30 years 37, above 30 years 24, total 102; for no row: less than 20 years 109, 20 - 30 years 43, above 30 years 46, total 198; for total row: less than 20 years 150, 20 - 30 years 80, above 30 years 70, total 300)

Explanation:

Step1: Identify relevant values

Total with iron deficiency: $102$; 20+ with deficiency: $37 + 24 = 61$

Step2: Calculate probability

$\text{Probability} = \frac{\text{20+ with deficiency}}{\text{Total with deficiency}} = \frac{61}{102} \approx 0.60$

Answer:

C. 0.60
