Answer

Explanation:

Step1: Calculate theoretical probability

The total number of face - cards is $4 + 4+4=12$. The number of Queens is 4. So the theoretical probability $P_{theo}$ of choosing a Queen is $\frac{4}{12}=\frac{1}{3}$.

Step2: Identify experimental probability

From the table, the experimental probability $P_{exp}$ of choosing a Queen is $\frac{4}{15}$.

Step3: Compare probabilities

Find the difference between the theoretical and experimental probabilities: $\frac{1}{3}-\frac{4}{15}=\frac{5 - 4}{15}=\frac{1}{15}$. The experimental probability is less than the theoretical probability.

Answer:

The experimental probability is less than the theoretical probability. The theoretical probability of choosing a Queen is $\frac{1}{3}$ and the experimental probability is $\frac{4}{15}$.
