Class 10 Maths Probability | Impossible & Sure Events |

**Impossible & Sure Events:**

Probability of an event which is *impossible to occur is 0. Such an *event is called an **impossible event.**

Probability of an event which is *sure (or certain) to occur is 1. Such an event *is called a **sure event or a certain event**

**Numerical**: A jar contains lemon only. Malini takes out one fruit without looking into the bag. What is the probability that she takes out an apple? Also find probability of taking out a lemon?

**Solution**: Since jar has only lemons, Probability of talking out Lemon is 1, since it is sure that that item she will take out will be lemon.

Similarly since the jar doesn’t have Apple, Probability of taking out apple is 0.
