Question

draw a card from a box filled with numbered cards. cards are returned and shuffled after each selection. whats the probability of drawing a card with an even number?

Explanation:

Step1: Count total cards

Count the total number of cards. There are 14 cards in total.

Step2: Count even - numbered cards

Count the number of even - numbered cards. There are 5 even - numbered cards (10, 10, 0, 0, 0).

Step3: Calculate probability

The probability formula is \(P=\frac{\text{Number of successes}}{\text{Total number of trials}}\). Here, \(P = \frac{5}{14}\approx0.36\) (converted to percentage: \(0.36\times100 = 36\%\))

Answer:

36%
