jasmine rolls a number cube 72 times. the number 2 is rolled 13 times and the number 3 is rolled nine times. to the nearest whole percent, what is the experimental probability of rolling a 2 or 3?\no 7%\no 18%\no 22%\no 31%

Answer

Explanation:

Step1: Calculate total favorable outcomes

The number 2 is rolled 13 times and the number 3 is rolled 9 times. So the total number of times a 2 or 3 is rolled is $13 + 9=22$.

Step2: Calculate experimental - probability formula

The experimental - probability $P$ is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of trials}}$. Here, the total number of trials is 72. So $P=\frac{22}{72}$.

Step3: Convert to percentage

$P=\frac{22}{72}\times100%=\frac{2200}{72}% \approx 30.56%$. Rounding to the nearest whole percent gives 31%.

Answer:

31%
