Probability - CCEA GCSE Statistics quiz quiz

A probability can take any value:

The theoretical probability of rolling an even number on a fair dice is:

A coin is flipped 80 times and lands heads 36 times. The relative frequency of heads is:

If $P(A) = 0.3$, then $P(\text{not } A)$ is:

For two mutually exclusive events, $P(A \text{ or } B)$ equals:

For two independent events, $P(A \text{ and } B)$ equals:

On a tree diagram, to find the probability of a single path you:

A bag has 4 red and 6 blue. One is taken and not replaced. After a red, $P(\text{red})$ on the second pick is:

Two mutually exclusive events are events that:

Expected frequency is calculated as:

A dice with $P(\text{six}) = \dfrac{1}{6}$ is rolled 300 times. The expected number of sixes is:

On a Venn diagram, the overlap (intersection) of two sets represents:

Relative frequency becomes a more reliable estimate of probability when:
