A card will be picked at random from a standard deck of 52​ cards. What is the probability that the value of the selected card is less than 5​?

Answer:

Step-by-step explanation:

In a standard deck of 52 cards, the values range from 2 to 10, along with the face cards (Jack, Queen, King) and the Ace. The cards that have a value less than 5 are 2, 3, and 4.

Each of these values (2, 3, and 4) appears in each of the four suits: hearts, diamonds, clubs, and spades. Thus, there are:

- 4 cards of value 2

- 4 cards of value 3

- 4 cards of value 4

So, the total number of cards with a value less than 5 is:

\[ 4 (for\ 2) + 4 (for\ 3) + 4 (for\ 4) = 12 \]

The probability of drawing one of these cards from a standard deck of 52 cards is the ratio of the number of favorable outcomes to the total number of possible outcomes:

\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} = \frac{12}{52} \]

Simplify this fraction:

\[ \frac{12}{52} = \frac{3}{13} \]

Therefore, the probability that the value of the selected card is less than 5 is:

\[ \frac{3}{13} \]
