1 answer

To determine the largest discrepancy between the experimental and expected probabilities in Jade's experiment, we first need to compute both the experimental probabilities from the given frequencies and the expected probabilities if each outcome were equally likely.

Step 1: Total Frequency

First, we calculate the total number of tosses:

\[ \text{Total Frequency} = 10 + 9 + 6 + 15 + 13 + 8 = 61 \]

Step 2: Experimental Probabilities

Next, we find the experimental probabilities for each outcome by dividing the frequency of each outcome by the total frequency:

\[ \text{P(2)} = \frac{10}{61} \approx 0.1639 \]

\[ \text{P(4)} = \frac{9}{61} \approx 0.1475 \]

\[ \text{P(6)} = \frac{6}{61} \approx 0.0984 \]

\[ \text{P(8)} = \frac{15}{61} \approx 0.2459 \]

\[ \text{P(10)} = \frac{13}{61} \approx 0.2131 \]

\[ \text{P(12)} = \frac{8}{61} \approx 0.1311 \]

Step 3: Expected Probabilities

Assuming each outcome (2, 4, 6, 8, 10, 12) is equally likely, the expected probability for each would be:

\[ \text{Expected Probability} = \frac{1}{6} \approx 0.1667 \]

Step 4: Discrepancies

Now, we calculate the discrepancies for each outcome by taking the absolute difference between the experimental and expected probabilities:

\[ \text{Discrepancy for 2} = |0.1639 - 0.1667| \approx 0.0028 \]

\[ \text{Discrepancy for 4} = |0.1475 - 0.1667| \approx 0.0192 \]

\[ \text{Discrepancy for 6} = |0.0984 - 0.1667| \approx 0.0683 \]

\[ \text{Discrepancy for 8} = |0.2459 - 0.1667| \approx 0.0792 \]

\[ \text{Discrepancy for 10} = |0.2131 - 0.1667| \approx 0.0464 \]

\[ \text{Discrepancy for 12} = |0.1311 - 0.1667| \approx 0.0356 \]

Step 5: Largest Discrepancy

After calculating all the discrepancies, we find the largest discrepancy:

  • For outcome 8: 0.0792 is the highest.

Thus, the outcome value with the largest discrepancy between the experimental and expected probability is 8, with a discrepancy of approximately 0.0792.
