iacst-2022

The last chapter of NCERT Class 9 maths begins with the simple introduction of the Probability topic, which is a chapter that deals with chances. Here, the probability of an event taking place or prize being won in a lottery system is calculated and known. One basis point regarding this chapter is that the probability an event might happen or might not; that means there is uncertainty in the event, and the chapter calculates the chance of that event. Various problems have been detailed out to understand the concept of probability. In the end, the topic deals with the concept of probability through different methods.

  • Probability is the uncertainty of an event taking place and not.
  • Famous philosophers Pascal and Fermat solved such problems independently that led to the formation of the probability theorem.
  • Activities are mentioned in the chapter to understand the concept of probability with live examples.
  • Calculating the probability for the combined groups is often known as Cumulative Probability.
  • If a coin is flipped twice in the air, the chances of getting no head or no tail increases.
  • The concept of Empirical probability has also been briefed out.
  • Experimental probability can be defined as the ratio of the number of outcomes that a specified event occurs in the total number of trials.
  • In the end, the chapter presents various types of problems to improvise the concept of probability.
