Explanation / Answer

1)probability =1043/1046=99.7%

2) probability =(3950/4000)*(3949/3999)*(3948/3998)*(3947/3997)*(3946/3996)=93.9%

3)

probability=(75+13+264)/367= 95.9%

4)

P(A|B) =0.0025*0.85/(0.0025*0.85+0.9975*0.1)=2.09%

P(A'|B') =0.9975*0.9/(0.0025*0.15+0.9975*0.9)=100.0%

respond refused total 18-21 75 13 88 22-29 264 15 279 total 339 28 367
