you pick a card at random. what is p(3)? write your answer as a percentage.

Explanation:

Step1: Determine total number of outcomes

There are 4 cards, so the total number of possible outcomes is 4.

Step2: Determine number of favorable outcomes

There is 1 card with the number 3, so the number of favorable outcomes is 1.

Step3: Calculate probability as a fraction

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(3)=\frac{1}{4}$.

Step4: Convert fraction to percentage

To convert $\frac{1}{4}$ to a percentage, we do $\frac{1}{4}\times100% = 25%$.

Answer:

25%
