1. ## Probabilities

Hello,
I have attached a PDF document that i am revising for my exams and have few questions.
Firstly i need confirmation that the answer for question 4) is
1/7, 3/28, 3/28, 5/28, 1/28, 1/7, 1/14, 1/28, 1/28, 1/28, 1/14, 1/28
since they all add up to one then it should be right......?
Secondly, i need help in working out and understanding 4)(ii) and 4)(iii).
