Explanation / Answer

Solution:

total number of cards = 52

( a )

number of 4s in a deck = 4

number of 9s in a deck = 4

probability of selecting a 4 or a 9 = ( 4 + 4 ) / 52 = 0.1538

( b )

number of 4s in a deck = 4

number of 9s in a deck = 4

number of 10s in a deck = 4

probability of selecting a 4 or a 9 or a 10 = ( 4+ 4+4 ) / 52 = 0.2307

( c )

number of 5s in a deck = 4

number of spades in a deck = 13

number of 5 of spades in a deck = 1

probability of selecting a five or spades = ( 4 + 13 - 1 ) / 52 = 16 / 52 = 0.3076
