among group of 2500 people 35% municipal bond,18% oil stock 7 % both if 1 person is to be ranmdomly selected from 2500 what is probabityt that a person selected will be one invest in municipal but not in oil stocks

• total people=2500
  muncipal bond=35% of 2500=875
  oil stock=18% of 2500=450
  7% both=175
  now only muncipal bond=875-175=700
  only oil stock=450-175=275
  so the muncipal but nt stock=700/2500=7/25

• from ven-diagram only municipal men=35-7=28%
  so probability of the person is from municipal but not oil stock = 28/100=7/25

• Ans=7/25
  % investment in both=7, Only in Municipal bond=(35-7)=28, Only Oil Stock=(18-7)=11
  % of total people invested=7+28+11=46,
  So out of 2500,people invested=2500*46/100=1150
  No.of people who invested in municipal bond but not in oil stocks=28*1150/46=700
  SO its Probability among 2500 people= 700/2500= 7/25
