Probability is the extent to which an event is likely to occur, like drawing a jack of hearts from a deck of cards or picking a red candy from a pack of assorted candies, etc. Probability is used to make decisions when one is not sure about the outcome.
- Tossing a coin: There can two possible outcomes i.e. Heads (H) and Tails (T) whenever a coin is tossed. The probability of getting a Head (H) and the probability of getting a Tail (T) is same which is ½.
- Throwing a Dice: When a dice is thrown, there can be only six possible outcomes i.e: 1,2,3,4,5,6. So, the probability of getting a 6 is same as getting a 2 or any other number i.e: 1/6. In simple words, the probability is “How likely something is to happen”. The students are required to solve several related questions to be able to solve the probability questions with ease.
