Understanding Probability with Math Antics

If a fair coin is flipped, what is the probability of landing on heads?

• 1/2

• 3/4

• 1/4

• 1/3

What does a probability of 1 indicate about an event?

• The event has a 50% chance of happening

• The event will definitely happen

• The event is impossible

• The event is unlikely

What does a probability less than one-half indicate about an event?

• It is certain to happen

• It cannot happen

• It is unlikely to happen

• It is likely to happen

How does conducting more trials affect the accuracy of probability results?

• Increases accuracy

• No effect

• Results become unpredictable

• Decreases accuracy
