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:
Empirical probability of deaths cause by stroke:
Percentage of deaths cause by stroke =0.4%
Empirical probability of deaths cause by kidney disease:
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.
Answer: B
Step-by-step explanation:
The answer to this is false
Answer:
31/36
Step-by-step explanation:
P(E or M) = P(E) + P(M) - P(E & M)
= (2/3) + (4/9) - (1/4)
= 31/36
