It would be 26 because half of 52 is 26 and because you are looking for the spades plus the hearts is u what that in half too and just want on or the other just divide 26 by 2

Answer:  0.5

Step-by-step explanation:

Given : The total number of cards in a deck = 52

Number of cards with hearts = 13

Number of cards with spade = 13

Probability of getting a card with heart :-

[tex]P(H)=\dfrac{13}{52}=\dfrac{1}{4}[/tex]

Probability of getting a card with spade :-

[tex]P(S)=\dfrac{13}{52}=\dfrac{1}{4}[/tex]

Since both the events are independent, then the probability that a heart or spade is chosen :-

[tex]P(H\ or\ S)=P(H)+P(S)\\\\=\dfrac{1}{4}+\dfrac{1}{4}\\\\=\dfrac{2}{4}=\dfrac{1}{2}=0.5[/tex]

Hence, the probability that a heart or spade is chosen = 0.5
