you roll a 6 - sided die. what is p(1 or odd)? write your answer as a percentage. %
Answer
Explanation:
Step1: Identify total and favorable outcomes
The total number of outcomes when rolling a 6 - sided die is $n = 6$ (the numbers 1, 2, 3, 4, 5, 6). The odd - numbered outcomes are 1, 3, 5. The event of getting a 1 is part of the event of getting an odd number. So the number of favorable outcomes for getting a 1 or an odd number is 3 (the numbers 1, 3, 5).
Step2: Calculate the probability
The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(1\text{ or odd})=\frac{3}{6}$.
Step3: Convert to percentage
To convert the fraction to a percentage, we use the formula $\text{Percentage}=P\times100%$. So $\frac{3}{6}\times100% = 50%$.
Answer:
50%
