you roll a 6 - sided die. what is p(prime)? write your answer as a fraction or whole number.
Answer
Explanation:
Step1: Identify prime - numbers on a 6 - sided die
The numbers on a 6 - sided die are 1, 2, 3, 4, 5, 6. Prime numbers among them are 2, 3, 5.
Step2: Calculate the probability
The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. The total number of outcomes when rolling a 6 - sided die is 6. The number of favorable outcomes (prime numbers) is 3. So $P(\text{prime})=\frac{3}{6}=\frac{1}{2}$.
Answer:
$\frac{1}{2}$
