Question

lorena has a jar of coins. she chooses a coin at random, notes what type of coin it is, and returns it to the jar. in the first 10 trials, lorena chooses a dime 3 times.
what is the experimental probability of choosing a dime based on the first 10 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 (choosing a dime) = 3, total trials = 10
$\text{Probability} = \frac{3}{10}$

Answer:

$\frac{3}{10}$ or 0.3
