1-.15= .85 or 85%
15% tall
85% short
t(n)=100%
P(short man)=85/100=17/20
85% short
t(n)=100%
P(short man)=85/100=17/20
1-. 15=. 85 or 85 percent
Total pr(e) =100%
Pr(tall)=15%
Total pr(e)=100%
:-total pr(e)-pr(tall)=pr(short)
100%-15%=85%
:-pr(short)=(85/100)%
Pr(short)=17/20
Pr(tall)=15%
Total pr(e)=100%
:-total pr(e)-pr(tall)=pr(short)
100%-15%=85%
:-pr(short)=(85/100)%
Pr(short)=17/20
