Answer

Explanation:

Step1: Recall experimental - probability formula

Experimental probability (P=\frac{\text{Number of favorable outcomes}}{\text{Total number of trials}})

Step2: Calculate for the first 10 trials

In the first 10 trials, the number of times a dime is chosen (favorable outcomes) is 3, and the total number of trials is 10. So the experimental probability (P_1=\frac{3}{10}=0.3)

Step3: Calculate for 11 trials

After the 11 - th trial, the number of times a dime is chosen (favorable outcomes) is (3 + 1=4), and the total number of trials is (10+1 = 11). So the experimental probability (P_2=\frac{4}{11})

Answer:

The experimental probability for the first 10 trials is 0.3. The experimental probability for all 11 trials is (\frac{4}{11})
