   Hi,
   
   Can anyone please explain the difference between part (1) and (2). I had a look at the examiners report but still can't clear the confusion in my mind.
   
   Thanks

   part (i) is where we'regiventhe time that the first claim occurs.
   
   Hence it is a conditional probability.
   
   Part (ii) doesn't specify the time - and so essentially we are using the "law of total probability" from CT3 to sum up the conditional probabilities to get the total probability for all times.
