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

Answer:

50%

Explanation:

Step1: Count total cards

There are 8 cards in total.

Step2: Count even - numbered cards

Even - numbered cards are 2, 4, 6, 8. So there are 4 even - numbered cards.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, $P(\text{even})=\frac{4}{8} = 0.5$.

Step4: Convert to percentage

To convert 0.5 to a percentage, we multiply by 100: $0.5\times100 = 50%$.
