Solution

what is the probability of getting a red king card in a deck of cards

Solution

\frac{1}{26}

Solution steps

Find the probability of getting red:

\frac{1}{2}

Find the probability of getting king:

\frac{1}{13}

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}{2} \cdot \frac{1}{13}

\frac{1}{2} \cdot \frac{1}{13} = \frac{1}{26}

= \frac{1}{26}
