2) option A is correct

3) optionA is correct

4)probabiliyt =1-0.157 =0.843

hence option A

5) as there are 10 even number and 7 number multipple of 3 and 3 for both

therefore probability =(10+7-3)/21 =14/21 =2/3

option A

6)probability =(161+74)/1164 =0.202

option A

7)probability =0.55*0.55 =0.303

option C
