Problem Analysis:
The problem involves comparing the
experimental probability and the
theoretical probability of drawing the Queen of Hearts from a standard 52-card deck. Here's a breakdown of the task:
1.
Experimental Probability: This is calculated based on the results of an experiment. In this case, a card is drawn and replaced 200 times, and the Queen of Hearts is drawn 5 times.
- Formula:
\[
\text{Experimental Probability} = \frac{\text{Number of times the event occurs}}{\text{Total number of trials}}
\]
2.
Theoretical Probability: This is calculated based on the inherent properties of the deck. Since there is only one Queen of Hearts in a standard 52-card deck, the probability of drawing it in a single draw is:
- Formula:
\[
\text{Theoretical Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}
\]
3.
Comparison: We need to determine which probability (experimental or theoretical) is higher.

Step-by-Step Solution:
#### 1. Calculate the Experimental Probability:
- The event of interest is drawing the Queen of Hearts.
- The number of times this event occurred is
5.
- The total number of trials is
200.
- Using the formula for experimental probability:
\[
\text{Experimental Probability} = \frac{5}{200} = 0.025
\]
- Convert to a percentage:
\[
0.025 \times 100 = 2.5\%
\]
#### 2. Calculate the Theoretical Probability:
- There is only
1 Queen of Hearts in a standard 52-card deck.
- The total number of possible outcomes when drawing a card is
52.
- Using the formula for theoretical probability:
\[
\text{Theoretical Probability} = \frac{1}{52}
\]
- Approximate the value:
\[
\frac{1}{52} \approx 0.01923
\]
- Convert to a percentage:
\[
0.01923 \times 100 \approx 1.923\%
\]
#### 3. Compare the Probabilities:
- Experimental Probability: \( 0.025 \) (or 2.5%)
- Theoretical Probability: \( \approx 0.01923 \) (or 1.923%)
Clearly, the experimental probability (\( 0.025 \)) is higher than the theoretical probability (\( \approx 0.01923 \)).

Final Answer:
\[
\boxed{\text{Experimental Probability is higher}}
\]
