Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
If you flip a fair coin, what is the probability of getting heads? Express your answer as a fraction.
[1 mark]2.
Calculate the probability of flipping a coin and getting tails twice in a row.
[2 marks]3.
A coin is used in a game to decide which animal to observe in a nature reserve. Heads means observing a bird, tails means observing a mammal. What is the probability that the next observation will be a bird?
[2 marks]4.
Construct a diagram on the grid to show all possible outcomes when flipping a coin twice.
[2 marks]5.
A researcher flips a coin 50 times in a forest to record bird sightings. If the coin is fair, how many times would you expect to see heads?
[2 marks]6.
In a particular environment, a coin is weighted so that the probability of heads is 3/4. What is the probability of getting tails?
[2 marks]7.
Explain why the probability of getting heads and tails on a fair coin are equal. Use environmental examples to support your explanation.
[3 marks]8.
A coin is flipped three times. What is the probability of getting exactly two heads?
[3 marks]9.
In an environmental survey, a coin is used to decide between two plant species. If the coin shows heads, the researcher observes species A; tails, species B. If the researcher flips the coin three times, what is the probability that exactly two observations are of species A?
[3 marks]10.
A student claims they can predict the outcome of a coin flip based on environmental factors such as wind or temperature. What is the scientific flaw in this reasoning? Explain briefly.
