<span>K) = 4/51 since there are four aces in the deck but only 51 cards left after the king has been removed. WITH REPLACEMENT: Find the probability of drawing three queens in a row, with replacement. We pick a card, write down what it is, then put it back in the deck and draw again.</span>

Probability is the ratio of no. of favorable/desired outcomes to the total outcomes possible, in this case desired outcome is king. As there are 4 kings, so favorable outcomes are 4. Now as there are 52 cards, so there can be 52 outcomes in total.
so probability of choosing a king is = 4/52.

<h3>Answer: $3\sqrt{7}$ </h3>

3*sqrt(7)

3 times the square root of 7

====================================================

Explanation:

I'm assuming the V stands for square root. You can write sqrt(63).

$\sqrt{63} = \sqrt{9*7}\\\\\sqrt{63} = \sqrt{9}*\sqrt{7}\\\\\sqrt{63} = 3\sqrt{7}$

The idea is to factor 63 in such a way that one factor is the largest perfect square possible, that way we can pull the root apart to simplify as shown above. The rule I used for the second step is $\sqrt{x*y} = \sqrt{x}*\sqrt{y}$
