(i) a card of spades or an ace (ii) a red king (iii) either a king or a queen (iv) nether a king nor a queen.

Answer 1

1)number of possible outcomes
= 13+3
=16
probability of getting a spade or ace
=16/52
=4/13
2)number of possible outcomes=2
probability of getting a red king
=2/52
=1/26
3)number of possible outcomes
=52-4-4
=44
probability of getting neither a king nor queen
=44/52
=11/13
4)number of possible outcomes
=4+4
=8
probability of getting either a king or a queen
=8/52
=2/13
