If you randomly select a card from a well-shuffled standard deck of 52 cards, what is the probability that the card you select is a 7 or 5? (Your answer must be in the form of a reduced fraction.)

Respuesta :

In a deckk of 52 cards there are four 5 and four 7, so the probability to select randomly a 5 or a 7 is:

[tex]\begin{gathered} \text{prob}=\frac{success\text{ cases}}{total\text{ cases}} \\ \text{prob}=\frac{8}{52}=\frac{2}{13} \end{gathered}[/tex]

The probability is 2/13
