# Probability (Complementary events)

Find the complementary probability:

- If you flip a coin P(heads) is $\dfrac{1}{2}$. What is P(tails)?
- If you roll a die, P(5) is $\dfrac{1}{6}$. What is P(not 5)?
- If you roll a die, P(even number) is $\dfrac{1}{2}$. What is P(not even) or P(odd)?
- If your teachers is randomly choosing a student of the month, your probability of being chosen is $\dfrac{1}{32}$. What is the probability that you are not chosen?
- If your probability of winning a raffle is $\dfrac{1}{1,000}$, what is the probability that you do not win?
- If you randomly choose a student from a class, the probability that his or her favorite food is pizza is $\dfrac{5}{26}$. What is the probaility that, if you choose a random student from this class, what is the probability that his or her favorite food is something other than pizza?
