In a standard deck of 52 cards, there are 13 diamonds and 12 face cards (4 Queens, 4 Jacks and 4 Kings)
Note that in each type of face cards, there is 1 diamond.
So we have : 10 diamonds and 12 face cards.
The probability is :
[tex]\begin{gathered} p=\frac{10+12}{52}=\frac{22}{52} \\ p=0.423 \end{gathered}[/tex]The answer is C. 0.423
