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?\n7%\n18%\n22%\n31%

Answer

Explanation:

Step1: Find total rolls of 2 or 3

Add the number of times 2 and 3 are rolled. $13 + 9=22$

Step2: Calculate experimental probability

Divide the total rolls of 2 or 3 by total rolls and multiply by 100. $\frac{22}{72}\times100=\frac{2200}{72}\approx30.56$

Step3: Round to nearest whole percent

$30.56\approx31$

Answer:

31%
