Question


MATH 1330 CHAPTER 5 BLACK_BOARD ASSIGNMENT Problem #3: B older) get the fl approximately 12.5% of the US population that i 65 year old or older, what is the probability that ased on the Statistical Abstract of the United States. About 14% of the senior citizens (65 and u each year and about 24% of the US population under 65 get the flu each year. If there are A. probability that a person from the population is 65 or over and will get the flu? Answer B. probability that a person from the population is under the age of 65 and will get the flu? Answer e that a particular community is made up of 95% seniors calculate the probabilities of parts C. Now assum (A and B) A.(65 and over) Answer B. ( under 65) Answer D. Assume that a community is made up of 50 A.(65 and over) Answer B. ( under 65) Answer

Explanation / Answer

Ans:

Given that

P(flu/above 65)=0.14

P(flu/under 65)=0.24

P(above 65)=0.125

P(under 65)=1-0.125=0.875

a)P(above 65 and flu)=P(flu/above 65)*P(above 65)=0.14*0.125=0.0175

b)P(under 65 and flu)=P(flu/under 65)*P(under 65)=0.24*0.875=0.21

c)Now,P(above 65)=0.95

P(under 65)=1-0.95=0.05

P(above 65 and flu)=P(flu/above 65)*P(above 65)=0.14*0.95=0.133

P(under 65 and flu)=P(flu/under 65)*P(under 65)=0.24*0.05=0.012

d)Now,P(above 65)=0.5

P(under 65)=0.5

P(above 65 and flu)=P(flu/above 65)*P(above 65)=0.14*0.5=0.07

P(under 65 and flu)=P(flu/under 65)*P(under 65)=0.24*0.5=0.12
