Question

select the correct descriptor of the following problems: from a pack of 52 cards, two cards drawn together at random. What is the probability od both the cards being kings?​

Answer 1

Answer:

$\frac{1}{221}$

Step-by-step explanation:

We have to note that there are 4 kings in a deck of 52 cards.

This makes the probability of choosing a king the first time $\frac{4}{52} = \frac{1}{13}$.

We now know that we can choose another king from the deck, but it's important to note that it's not a $\frac{1}{13}$ chance. We now only have 51 cards in the deck, and 3 kings left. This means the probability of choosing a king now is $\frac{3}{51} = \frac{1}{17}$.

To find the probability of doing both these, we need to multiply the fractions.

$\frac{1}{13}\cdot\frac{1}{17}=\frac{1}{221}$

Hope this helped!
