one person is to be selected from grp of 25 ppl. the probability tht selected person will be male is 0.44 and probability tht selected person will be male who was born before 1960 is 0.28. what is the no of males in the group who were born in 1960 or later??

• x/25=0.44=>no of persons will be male is x=11,
  x/25=.28=>no of persons will be male born before 1960=0.28*25=7.
  so 11-7=4 will be the no of male who were born in 1960 or later.

• 0.44 males in 25 ppl is : (25*0.44) = 11
  0.28 people who was before 1960: (11*0.28)=3.08
  no of males in group who were born in 1960 or later =11-3 = 8
