Choose the one alternative that best completes the statement or answers the question.
-Suppose that the sample space is $S = \{ 1,2,3,4,5,6,7,8,9,10 \rangle$ and that outcomes are equally likely. Compute the probability of the event $E = \{ 2,10 \}$.
A) 2
B) $\frac { 1 } { 5 }$
C) $\frac { 1 } { 10 }$
D) $\frac { 2 } { 9 }$

Question

Quizplus · Accepted Answer

The probability of event E is calculated by dividing the number of favorable outcomes by the total number of outcomes in the sample space. Here, there are 2 favorable outcomes (2 and 10) out of a total of 10 outcomes, so the probability is $\frac{2}{10} = \frac{1}{5}$.
