A survey of 10 students found that 5 students preferred art, 2 preferred history, and 3 preferred science. What is the probability that a student preferred science?
The table shows the results of a survey that asked 30 students to vote for their favourite sport.

What is the probability that a randomly selected student voted for basketball?
Fares has bought a tetrahedral die that has the values 1 to 4 on its faces. He wants to investigate whether the die is fair, so he decides to roll it 100 times and record all the values in a table. He gets the following results.
What is the theoretical probability of rolling a 2, assuming that the die is fair?
What is Fares’s experimental probability for rolling a 2?
Does the difference in these two probabilities mean that the die is most likely to be biased or unbiased?
