<em>Complete Question:</em>
<em>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 10?</em>
Answer:
Step-by-step explanation:
Given
Number of Sides = 12
Required
Probability of obtaining a side greater than 10
We start by listing out the sample space;
Next, we list out digits greater than 10; Represent this with T
Probability of T is calculated as follows;
Divide the numerator and denominator by 2
<em>Hence, the required probability is </em><em />
