a twelve - sided die with sides labeled 1 through 12 will be rolled once. each number is equally likely to be rolled. what is the probability of rolling a number greater than 9? write your answer as a fraction in simplest form.
Answer
Explanation:
Step1: Determine total outcomes
The die has 12 sides, so the total number of possible outcomes is 12.
Step2: Determine favorable outcomes
Numbers greater than 9 on a 1 - 12 die are 10, 11, 12. So there are 3 favorable outcomes.
Step3: Calculate probability
The probability $P$ of an event is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P = \frac{3}{12}$.
Step4: Simplify the fraction
$\frac{3}{12}=\frac{3\div3}{12\div3}=\frac{1}{4}$.
Answer:
$\frac{1}{4}$
