If you draw a card out of a deck of cards at random, what is the probability

LekaFEV [45]

Answer:

$\frac{1}{13}$

Step-by-step explanation:

Probability is the number of favorable outcomes divided by the number of total outcomes. The total outcomes are all the situations that could possibly happen. There are 52 cards in the deck, so there are 52 total outcomes. Next, the favorable outcomes are the outcomes we want. In this case it is drawing a 6. There are four 6's in a deck of cards: 6 of hearts, 6 of spades, 6 of diamonds, and 6 of clubs. This means there are 4 favorable outcomes.

We can write the probability as a fraction: $\frac{favorable-outcomes}{total-outcomes}$ , so we can get $\frac{4}{52}$ . Since both 4 and 52 are divisible by 4, the fraction can be simplified to $\frac{1}{13}$ .
