Chances and Probability
It often happens that we take up a chance in predicting some events or happenings that we come across in everyday life. Here are some daily life examples where we take up a chance.

• Chances that it would rain on a sunny day or not. • Chances that he/she wins or loses a game. • Chances that the train would arrive late to the station. • Chances of getting an expected question in the examination. • Chances that a political party wins or loses in the election. • Chances of getting a head or a tail in tossing a coin. • Chances that we would win in a lottery. • Chances of drawing the expected card from the deck, etc. How do we relate chance and probability?

Probability is a mathematical term of expressing the chance or predicting the happening of an event mathematically.

Consider the example of playing cards, the probability that the drawn card is a king of hearts is given by $$\frac{1}{52}$$ where $$52$$ is the total number of cards in a deck.

Thus, chances and probability are related to real-life right from childbirth in predicting whether the baby is a boy or a girl to the person's death, whether death is natural or accidental.
