what is the probability that randomaly selected four digit no is divisible by 8

• A no is divisible by 8 if its last three no's are divisible by 8.
  
  Hence in a 4 digit no Say ABCD if BCD is Divisible by 8 then ABCD is also Div by 8
  
  So Total no of possibility of 4 digit no which are to be considered
  
  =1000 (i.e A000-A999)
  
  Total Cases(Favourable) Divisible by 8 = 1000/8 =125
  
  Hence Probability = 125/1000
  = 1/8.

• Sample space= 9000
  No. of favourable events= 1125
  so ans= 1125/9000
  => 1/8
