Answer:
Probability is:   
Step-by-step explanation:
From a deck of 52 cards there are 26 black cards. (Spades and Clubs).
Also, there are 26 red cards. (Hearts and Diamonds).
First, we determine the probability of drawing a black card.
P(drawing a black card) =  
  
Now, since we don't replace the drawn card, there are only 51 cards.
But the number of red cards is still 26,
∴ P(drawing a red card) =  
  
Now, the probability of both black and red card =  
 

Hence, the answer.
 
        
             
        
        
        
Y=1 because if you remove the y’s, you see 1.4+0.09=1.49
