The probability of occurrence of two events E and F are 0.25 and 0.30 respectively. The probability of their simultaneous occurrence is 0.14. The probability that either E occurs or F occurs is

• Ans:.41
  p(E U F) = p(E) + P(F) - p(E ^ F)
  =.25+.30 -.14 =.41

• i guessed answer is 0.41

• the probablity of either E occurs or F occurs=P(E)*P(F') + P(F')*P(E)
  =0.25*0.70 + 0.75*0.30
  =0.40
  so probality of occurence of either events will be 0.40

• p(e)+p(f)-p(e&f)=>
  0.25+0.30-0.14=0.41

• It's 0.40 ... (i.e) 0.25*0.70 + (0.30*0.75)
  If u follow (EuF) rule that gives probability of occurance of both E and F

• p(EUF)=p(E)+p(f)-p(E^F)
  0.14=0.25+0.30-P(E^F)
  P(E^F)=0.41
