Tips and Tricks

• the distinction between AND and OR

It would be very important to read the problems and follow each step outlined in the question in order to solve probability questions more quickly. Understand what the issue is trying to tell us. When you solve the problem mathematically, AND, which links the events in the question, denotes multiplication, and OR, which denotes addition, should be utilized when linking the two occurrences.

• Imagine the issue.

If the logic is too complex to comprehend in your head alone, try visualizing your solution by expanding it to Venn Diagrams and sets. Venn Diagrams can occasionally be used to represent problems involving more than three or four events.

Probability Class 11 Key Notes

If there are multiple outcomes conceivable for an experiment and it is not possible to anticipate the results beforehand, the experiment is said to be a random experiment.

An experiment’s outcomes are all potential outcomes.

Let’s think about a die-rolling experiment. There are only the numbers 6, 5, 4, 3, and 1. The sample space, which is represented by the letter “S,” is the collection of all of these results: 6, 5, 4, 3, 2, 1.

Let’s think about a simple experiment where we toss two coins once. The outcomes are: First coin — Head and Second coin — Tail = HT, First coin — Tail and Second coin — Tail = HH, First coin — Tail and Second coin — Tail = TT, First coin — Tail and Second coin — Head = TH.

Thus, the sample space (S) can be represented as {HH, TT, HT, TH}.
