1. In order to draw meaningful inferences from any data, we need to organise the data pointsinformation systematically.

2. Data can also be presented using circlebar graph or piedouble chart.

3. A circle graph shows the relationship between a and its .

4. There are certain experiments whose outcomes have an equalnot equal chance of occurring.

5. A random experiment is one whose outcome cannot be predicteddepicted exactly in advance.

6. Outcomes of an experiment are equallynot equally likely if each has the same chance of occurring.

7. Probability of an event = Number of outcomes that make an eventTotal number of outcomes of the experiment

when the outcomes are equally likely.

8. One (or) moreTwoTwo (or) more outcomes of an experiment make an event.

9. Chances and probability are related to real life.
