A twelve-sided die with sides labeled through will be rolled once. Each number is equally likely to be rolled. What is the proba
FromTheMoon [43]

<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:

P(T) = \frac{1}{6}

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;

S = \{1,2,3,4,5,6,7,8,9,10,11,12\}

n(S) = 12

Next, we list out digits greater than 10; Represent this with T

T = \{11,12\}

n(T) = 2

Probability of T is calculated as follows;

P(T) = \frac{n(T)}{n(S)}

P(T) = \frac{2}{12}

Divide the numerator and denominator by 2

P(T) = \frac{1}{6}

<em>Hence, the required probability is </em>\frac{1}{6}<em />
