The cards Question In probability, what is an outcome? Tap to flip Answer A result of a trial. Question In probability, what is a trial? Tap to flip Answer A single predefined test. Question What does likelihood describe? Tap to flip Answer The chance that a particular event will occur. Question What is a sample space? Tap to flip Answer All the possible outcomes of a trial. Question What is a sample space diagram? Tap to flip Answer A systematic way of producing a sample space. Question When a fair dice is rolled, is a 6 less likely than the other numbers? Tap to flip Answer No. Rolling a dice is random, so all the outcomes are equally likely. Question In probability, what is an event? Tap to flip Answer A subset of a sample space: a particular outcome or a set of outcomes that may occur from a trial. Question Are the outcomes of a trial always equally likely? Tap to flip Answer No. Factors can make one outcome more or less likely than another, e.g. one tennis player's skill or experience. Question When is an outcome impossible? Tap to flip Answer When there is no possibility that it can happen. Question When is an outcome certain? Tap to flip Answer When it is guaranteed to happen. Question When does an outcome have an even chance? Tap to flip Answer When its likelihood of happening is the same as its likelihood of not happening. Question How many different likelihoods does the scale of likelihoods show? Tap to flip Answer 5 Question Does each number on a dice have an even chance of being rolled? Tap to flip Answer No. Each number is equally likely, but each has less than an even chance. Question In probability, what is an experiment? Tap to flip Answer A repetition of a trial multiple times to observe how often each outcome occurs. Question If a coin is flipped 10 times, do you always get the same number of heads and tails? Tap to flip Answer No. Even when outcomes are equally likely, one may happen more often than the others in a small number of trials. Question What does listing outcomes systematically mean? Tap to flip Answer Listing them in a way that ensures all outcomes are recorded. Question What is a benefit of listing outcomes systematically? Tap to flip Answer The likelihood of error is reduced. Question What is an outcome table? Tap to flip Answer A table that shows all the possible outcomes. Question In an outcome table for two events, can the rows and columns be swapped? Tap to flip Answer Yes, the rows and columns can be transposed. Question What does each branch of an outcome tree show? Tap to flip Answer A possible outcome from an event or from a stage of a trial. Question What does a full outcome tree show? Tap to flip Answer All the possible outcomes. Question In an outcome tree, what does the number of branches in each group reflect? Tap to flip Answer The number of outcomes of that stage of the trial. Question Must every group of branches in an outcome tree have the same number of branches? Tap to flip Answer No. Each stage may have a different number of outcomes, so groups can have different numbers of branches. Question In a Venn diagram, what is commonly used to represent events? Tap to flip Answer Circles. Question In a Venn diagram, what does the rectangle hold? Tap to flip Answer All the possible outcomes: the sample space. Question For an outcome table, what is the sample space? Tap to flip Answer The table itself. Question When must the sample space be constructed for a two-stage outcome tree? Tap to flip Answer After drawing the two layers of branches. Question How many layers of branches can an outcome tree have? Tap to flip Answer As many as needed, depending on the number of stages in the trial. Question How many layers of branches would an outcome tree for flipping 7 coins have? Tap to flip Answer 7 Question Into how many events can a single outcome table categorise outcomes? Tap to flip Answer Only two. Question Do outcome tables and outcome trees only work when all outcomes are equally likely? Tap to flip Answer No. Extra rows, columns or branches can show outcomes that are more or less likely than others.

How this deck was checked On 2026-11-03, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong.
