Solution involves the use of basic probability formulae, features of a deck of playing cards.
Permutations/combinations with and without repetitions are used.

In general, you should give your answers as fractions. Where you give an answer as a decimal, you should give it correct to four decimal places.
(a) In this part of the question, state which rule of probability you use for each calculation.
A standard pack of 52 playing cards is shuffled thoroughly and then cut. The pack is then shuffled and cut for a second time. Within the pack, a 'picture' card is defined to be a card showing an ace, king, queen or jack (that is, not a card showing any of the numbers 2, 3,... , 10).
(i) Find the probability that the first time the pack is cut, the card displayed is a picture card.
Solution: There are four suits (clubs (♣), diamonds (♦), hearts (♥) and spades (♠)) in any standard pack of 52 cards. Each suit has 13 cards in it. Each suit contains four picture cards. Hence there are 16 picture cards in a standard pack of 52 playing cards. Remaining ...
