When an action is performed, an outcome of that action results. But if
the action performed may give more than one result, the prediction of the
exact result becomes difficult.
For example, if a die is thrown then one of the six faces of the die
will appear on the top and so there will be six possible outcomes.
Probability is the study of uncertain results. If a coin is tossed there
are two possibilities, either a head will come or a tail.
Thus, probability of occurrence of a
head in a single toss is
1. If one card is drawn at random from a pack of 52 regular playing
cards, what is the probability of getting an Ace or a Jack?
