P(`barA`)=(Favourable number of elementary events to event `bar A`) / (Total number of elementary events).

favorable elementary events

Define an elementary event.

A coin is tossed.Find the total number of elementary events and also the total number evpents associated with the random experiment.

Elementary an outcome of a random experiment is called an elementary event.

A pair of dice is rolled.If the outcome is a doublet,a coin is tossed.Determine the total number of elementary events associated to this experiment.

Favourable elementary event an elementary event is said to be favourable to a compound event A if it satisfies the definition of the compound.

If A is a sure event, then P(barA) is.

Two numbers are successively drawn from the set {1, 2, 3, 4, 5, 6, 7} without replacement and the outcomes recorded in that order. What is the number of elementary events in the random experiment ?
