Answer:
The probability that the individual is between 70 and 80 years of age is [tex]\frac{16}{63}[/tex].
Step-by-step explanation:
Given frequency table:
Ages Frequency
30 up to 40 14
40 up to 50 3
50 up to 60 10
60 up to 70 20
70 up to 80 16
Total 63
We need to find the probability that the individual is between 70 and 80 years of age.
[tex]P=\frac{\text{Total number of individuals between 70 and 80 years of age}}{\text{Total number of individuals}}[/tex]
Total number of individuals between 70 and 80 years of age = 16
Total number of individuals = 63
[tex]P=\frac{16}{63}[/tex]
Therefore the probability that the individual is between 70 and 80 years of age is [tex]\frac{16}{63}[/tex].
