Question

you roll a 6 - sided die. what is p(not prime)? write your answer as a percentage rounded to the nearest tenth.

Explanation:

Step1: Identify total outcomes

The total number of outcomes when rolling a 6 - sided die is $n = 6$ (the numbers 1, 2, 3, 4, 5, 6).

Step2: Identify non - prime numbers

The non - prime numbers on a 6 - sided die are 1, 4, 6. So the number of non - prime outcomes $m=3$.

Step3: Calculate the probability

The probability formula is $P=\frac{m}{n}$. So $P(\text{not prime})=\frac{3}{6}=0.5$.

Step4: Convert to percentage

To convert to a percentage, we multiply by 100. So $0.5\times100 = 50.0\%$.

Answer:

$50.0\%$
