Answer:

[tex]\sf D) \quad \dfrac{1}{64}[/tex]

Step-by-step explanation:

[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]

Probability of drawing a heart from one deck:

[tex]\sf \implies P(heart)=\dfrac{1}{4}[/tex]

Therefore, probability of drawing a heart from each of 3 decks:

[tex]\sf \implies P(heart)\:and\:P(heart)\:and\:P(heart)=\dfrac{1}{4} \times \dfrac{1}{4} \times \dfrac{1}{4}=\dfrac{1}{64}[/tex]
