The population of the country was 314 million. What is the empirical probability of death by stroke during a single​ year
Marat540 [252]

Answer:

Empirical probability of deaths cause by stroke=0.004086

Empirical probability of deaths cause by kidney disease =0.001436

Death rate due to stroke is 4 times the death rate due to kidney disease.

Step-by-step explanation:

Consider the table attached in figure

No. of deaths cause by stroke = 128300

No. of deaths caused due t kidney disease = 45100

Total population = 314 x 10⁵

Formula to calculate empirical probability:

P(A)=\frac{No.\, of\,\, times\,\, event\,\, occurs}{Total\,\, population}\\

Empirical probability of deaths cause by stroke:

P(A)=\frac{128300}{314\times 10^5}\\\\P(A)=0.004086

Percentage of deaths cause by stroke =0.4%

Empirical probability of deaths cause by kidney disease:

P(B)=\frac{45100}{314\times 10^5}\\\\P(B)=0.001436

Percentage of deaths cause by kidney disease =0.1%

Ratio between deaths caused to stoke to deaths caused by kidney disease is 4:1 which means death rate due to stroke is 4 times the death rate due to kidney disease.

How is 21\30 bigger then 2\3
strojnjashka [21]
By reducing 21/30 you dived 21 and 30 by 3 and you will get 7/10. Is 7/10 larger than 2/3? If we put these fractions in decimal form we will see 7/10 turns into 0.7 and 2/3 turns into 0.667. So the answer is 21/30 is larger than 2/3.
