Question

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? %

Explanation:

Step1: Calculate total favorable outcomes

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

Step2: Calculate experimental probability

The total number of rolls is 64. The experimental - probability formula is $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P=\frac{20}{64}$.

Step3: Convert to percentage

$P=\frac{20}{64}\times100\%=\frac{2000}{64}\% = 31.25\%$. Rounding to the nearest whole percent gives 31%.

Answer:

31
