zayden has a jar of coins. he chooses a coin at random, notes what type of coin it is, and returns it to the jar. in 15 trials, zayden chooses a penny 7 times.\nwhat is the experimental probability of choosing a penny based on the 15 trials?\n$\frac{7}{15}$\non the 16th trial, zayden chooses a nickel. what is the experimental probability of choosing a penny based on the 16 trials?
Answer
Explanation:
Step1: Recall experimental - probability formula
Experimental probability (P=\frac{\text{Number of favorable outcomes}}{\text{Total number of trials}})
Step2: Determine values for 16 - trial case
The number of times a penny was chosen in 16 trials is still 7 (since the 16th - trial was a nickel), and the total number of trials is 16. So, (P = \frac{7}{16})
Answer:
(\frac{7}{16})
