A card is drawn at random from a well-shuffled deck of playing cards. Find the probability that the card drawn is:
(i) a card of spades or an ace (ii) a red king (iii) neither a king nor a queen (iv) either a king or a queen

(i) There are 13 spades and 4 aces but ace spade is already included in the 13 spades so the no. of cards are 13+3=16
     Total no. of cards in the deck =  52
, P(E)=16/52
(ii) there are 2 red kings ( 1 diamond and 1 hearts)
  therefore, P(E)= 2/52=1/26
(iii) there are 4 king and 4 queens 
so a total of 8 cards
so 52-8=44 cards
P(nether a king nor a queen) = 44/52 = 22/26 = 11/13
(iv) P(either a king or queen) = 8/52 = 4/26 = 2/13

(i)17/52
(ii)1/52
(iii)44/52 (or) 11/13
(iv)8/52 (or) 2/13
