In 2012, there were 6.4% of people under 5 years of age, 23.5% of people under 18 years of age, and 13.7% of people 65 and older in the United States.What is the chance of randomly selecting a U.S. citizen under 5 years of age or over 65 years of age in 2012?

Respuesta :

The given probabilities are:

P(a<5 years)=6.4%/100%=0.064

P(a<18 years)=23.5%/100%=0.235

P(a>=65 years)=13.7%/100%=0.137

The chance of randomly select a U.S. citizen under 5 years of age or over 65 years of age is:

[tex]\begin{gathered} P(a<5)orP(a\ge65)=P(a<5)+P(a\ge65) \\ P(a<5)orP(a\ge65)=0.064+0.137 \\ P(a<5)orP(a\ge65)=0.201 \end{gathered}[/tex]

Answer: P=0.201
