Q. You pick a card at random.

\newline

1234

\newline

What is

P(1)

?

\newline

Write your answer as a percentage.

\newline

\_\_\_\%

Identify Total Cards: Identify the total number of cards and the specific event of interest. $\newline$ Total cards = $4$ (labeled $1$ , $2$ , $3$ , $4$ ) $\newline$ Cards labeled ' $1$ ' = $1$ $\newline$ Calculate the probability: $\newline$ $P(1) = \frac{\text{Number of favorable outcomes}}{\text{Total outcomes}}$ $\newline$ $= \frac{1}{4}$
Calculate Probability: Convert the probability to a percentage for the final answer. $\newline$ Percentage = $(\text{Probability}) \times 100$ $\newline$ = $\frac{1}{4}$ \times $100$ $\newline$ = $25\%$
