Question

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. what is the experimental probability of choosing a penny based on the 15 trials?

Explanation:

Step1: Define experimental probability

Experimental probability = $\frac{\text{Number of successful trials}}{\text{Total number of trials}}$

Step2: Plug in given values

Successful trials (penny picks) = 7, Total trials = 15
Expression: $\frac{7}{15}$

Answer:

$\frac{7}{15}$
