Pasos de solución

Find the probability of getting king:

\frac{1}{13}

Find the probability of getting heart:

\frac{1}{4}

Since the events are independent, Use the formula

P (X_{1} \land X_{2} \land \dots \land X_{k}) = P (X_{1}) \cdot P (X_{2}) \cdot \dots \cdot P (X_{k})

= \frac{1}{13} \cdot \frac{1}{4}

\frac{1}{13} \cdot \frac{1}{4} = \frac{1}{52}

= \frac{1}{52}
