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? 7% 18% 22% 31%

Answer

Explanation:

Step1: Calculate total rolls of 2 and 3

$13 + 9=22$

Step2: Calculate experimental probability

$\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{22}{72}$

Step3: Convert to percentage

$\frac{22}{72}\times100%\approx 30.56%$ Rounding to nearest whole - percent gives $31%$.

Answer:

D. 31%
