Combined event

A combined event joins outcomes from two or more stages. For example, you might toss a coin and roll a die, select two counters, or observe whether a bus is late on each of two days. The question may ask for one particular sequence, such as “red then blue”, or for several acceptable sequences, such as “one counter of each colour”.

A combined event joins outcomes from two or more stages, such as “roll a 6 and then obtain a head”. The word and requires one complete sequence of outcomes.
