Question

draw a card from a box filled with numbered cards. cards are returned and shufled after each selection. whats the probability of drawing a card with an even number? run trial ×1 run trial ×10 run trial ×100 total trials total successes percent success 0 0 0% 39% 47% 54% 62%

Explanation:

Step1: Count the total number of cards

Count the number of cards in the box. Let's assume there are 13 cards (by counting the visible ones).

Step2: Count the number of even - numbered cards

Assume the even - numbered cards are 6 (by identifying numbers like 0, 2, 4, 6, 8, 10 if they are present).

Step3: Calculate the probability

The probability formula is \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). Here, the number of favorable outcomes (even - numbered cards) is \(n = 6\), and the total number of outcomes (total cards) is \(N=13\). The probability as a percentage is \(P=\frac{6}{13}\times100\%\approx 46.15\%\approx47\%\)

Answer:

47%
