finding experimental probability\npaige 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 the total number of times 3 or 4 appeared

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

Step2: Calculate the 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

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

Answer:

31%
