Question

what is the probability that a card drawn randomly from a standard deck of 52 cards is a nine? express your answer as a fraction

Answer 1

Given the question, we need to know that a standard deck contains 52 cards out of which there are 4 cards showing nine.

`\text{Probability = number of possible outcomes/number of total outcomes}`

To get the probability of randomly drawing a nine will be:

`\begin{gathered} \frac{n\text{ (nine)}}{n\text{ (total cards)}} \\ pr(nine)=(4)/(52)=(1)/(13) \end{gathered}`

Hence, the probability of drawing nine is 1/13
