paige rolls a number cube sixty - four times. the number 4 comes up fourteen times. the number 3 comes up six times. rounded to the nearest whole percent, what is the experimental probability of rolling a 3 or 4? \n%

Answer

Explanation:

Step1: Find total number of 3s and 4s

The number 4 comes up 14 times and the number 3 comes up 6 times. So the total number of times 3 or 4 comes up is $14 + 6=20$.

Step2: Calculate experimental probability

The experimental - probability $P$ is the number of favorable outcomes divided by the total number of outcomes. The total number of rolls is 64. So $P=\frac{20}{64}$.

Step3: Convert to percentage

$P=\frac{20}{64}\times100%=\frac{2000}{64}% = 31.25%$.

Step4: Round to nearest whole percent

Rounding 31.25% to the nearest whole percent gives 31%.

Answer:

31%
