Consider an event X comprised of three outcomes whose probabilities are $\frac { 9 } { 18 }$ , $\frac { 1 } { 18 }$ , and $\frac { 6 } { 18 }$ . Compute the probability of the complement of the event.
A) $\frac { 2 } { 18 }$
B) $\frac { 1 } { 2 }$
C) $\frac { 16 } { 3 }$
D) $\frac { 16 } { 18 }$

Question

Quizplus · Accepted Answer

The probability of the event X is the sum of the probabilities of its outcomes, which is $\frac { 9 } { 18 } + \frac { 1 } { 18 } + \frac { 6 } { 18 } = \frac { 16 } { 18 }$. The probability of the complement of the event is $1 - \frac { 16 } { 18 } = \frac { 2 } { 18 }$.
