Answer: [tex]\frac{13}{51}[/tex]
Step-by-step explanation:
Given: Number of cards in a standard deck = 52
If we already chosen a diamond card, then the number of cards left in the deck =52-1=51
The number of spades remains same = 13
Now, the probability that you choose a spade, given that you have already chosen a diamond is given by :-
[tex]P(Spade|diamond)=\frac{13}{51}[/tex]
Hence, the the probability that you choose a spade, given that you have already chosen a diamond [tex]=\frac{13}{51}[/tex]
