Question

If probability of winning a game is $p$, then probability of losing the game is:

• A. $1 + p$
• B. $-p$
• C. $p - 1$
• D. $1 - p$

Answer 1

Answer: (D)

$1 - p$

Answer 2

The total probability of all events must sum to 1. If the probability of winning is $p$, then the probability of losing is:

$1 - p$

Thus, the probability of losing the game is $1 - p$.
