Question

Events A and C are independent. If the probabilities relating A, B and C are P (A) = 1/5; P left parenthesis B right parenthesis equals 1 divided by 6 semicolon P left parenthesis A intersection C right parenthesis equals 1 divided by 20 semicolon P left parenthesis B union C right parenthesis equals 3 divided by 8 then

  1. events B and C are independent    
  2. events B and C are mutually exclusive    
  3. events B and C are neither independent nor mutually exclusive    
  4. events B and C are equiprobable    

The correct answer is: events B and C are independent
