Step by step explanation:
There are 13 diamond cards on a deck and for the other 3 suits there are 6 cards with a value less than 7 (including the ace) on each suit, so we have:
[tex]13+6+6+6=31\text{ possibilities}[/tex]The total amount on a deck is 52 cards, then the probability of selecting a diamond card or a card less than 7 is:
[tex]P=\frac{31}{52}[/tex]Answer: P=31/52
