• If a board result is declared, the chances to be the topper of the school is very unlikely as there is only one topper
                in the school.
              Impossible Events
              These events have no chance of occurring; they are not feasible outcomes. The event will never happen or is
              impossible, it will have a probability of 0. For example,

                 • Rolling a fair six-sided die to get a number greater than 6 or less than 1.
                 • Drawing a card from a standard deck and it turns out to be orange in colour.
                 • The probability that you can pick a red ball from a bag containing only blue balls is 0.
                 • Picking a random day of the week, and it turns out to be both Monday and Friday at the same time.
                 • Picking a guava in an orchard of apples.
                 • The probability of a fish to climb a tree is an impossible event.

              Equal Probability Events
              In this scenario, each event has an equal chance of occurring. For example,
                 • If you roll a fair six-sided die, the probability of rolling any specific number (1, 2, 3, 4, 5, or 6) is the same because
                each face of the die has an equal chance of landing face up.
                 • To guess a number between 1 and 10, each number has an equal probability of being selected.
                 • The chances of selecting a particular coloured marble from a bag of marbles containing the equal number of
                red, blue, and green marbles are equal.
                 • When students enter in a classroom and select their seats, each desk or chair has an equal chance of being
                chosen.
                 • Selecting a boy or a girl from a class having equal number of girls and number of boys has an equal probability.

              The probability of an event occurring is somewhere between impossible and certain. If an event is certain or sure
              to happen, it will have a probability of 1.

              For example, the probability of taking out a yellow ball from a box containing 10 yellow balls is 1. If an event
              will never happen or is impossible, it will have a probability of 0. For Example, taking out green ball from a box
              containing 10 yellow balls is 0.
              So, the probability of an event occurring lies between 0 and 1.
