Explanation / Answer

e)probabilty =(21000+190000+37000+8000+4000)/1774000 =0.2103

f) probability =(21000+190000+37000+8000+4000-10000)/1774000 = 0.2046

g)probabilty =(1024000/1774000)*(1024999/1774999)=0.3332

h)probability =1-0.3332=0.6668

i)probability =2*(1024000/1774000)*(1774000-1024000)/1774999=0.4878

j)=0.2938

k)1-0.2938 =0.7062
