Answer:

0.0588

Explanation:

There are 52 cards total in a pack of cards.

There are 13 diamond cards in a pack of card

When the first card is dealt, it is NOT replaced. When the second card is dealt, it is NOT replaced

In probability:

AND = multiplication

OR = addition

Probability =
(Total number of diamond cards)/(Total number of cards)

Probability that both friends for diamonds:

First card is DIAMONDS AND second card is DIAMONDS:

=
(13)/(52)×
(12)/(51)

=
(156)/(2652)

= 0.0588 (Rounded off to 3 significant figures)
