Example: At a car park there are vehicles, 60 of which are cars, 30 are vans and the remainder are lorries. If every vehicle is equally likely to leave, find the probability of: a a van leaving first. Solution: a Let S be the sample space and A be the event of a van leaving first. Probability of a van leaving first:.
Let T be the sample space and C be the event of a car leaving. Probability of a car leaving after a lorry or van has left:. Example: A survey was taken on 30 classes at a school to find the total number of left-handed students in each class. The table below shows the results:. A class was selected at random. Solution: a Let S be the sample space and A be the event of a class having 2 left-handed students.
Here, the sample space is the total number of students in the 30 classes, which was given as Let T be the sample space and C be the event that a student is left-handed. Example: ABCD is a square. A point is selected at random in the square.
Calculate the probability that it lies in the triangle MCN. Solution: Let 2x be the length of the square. Area of triangle MCN is. The following video shows some examples of probability problems. A few examples of calculating the probability of simple events. This video introduces probability and gives many examples to determine the probability of basic events. A bag contains 8 marbles numbered 1 to 8 a. What is the probability of selecting a 2 from the bag?
What is the probability of selecting an odd number? What is the probability of selecting a number greater than 6? Using a standard deck of cards, determine each probability. P face card b. P non face card. This video shows how to evaluate factorials, how to use permutations to solve probability problems, and how to determine the number of permutations with indistinguishable items.
A permutation is an arrangement or ordering. For a permutation, the order matters. This video shows how to evaluate combinations and how to use combinations to solve probability problems. A combination is a grouping or subset of items. For a combination, the order does not matter. This video explains how to determine the probability of different events.
This can be found that can be found using combinations and basic probability. A group of 10 students made up of 6 females and 4 males form a committee of 4. What is the probability the committee is all male? What is the probability that the committee is all female? What is the probability the committee is made up of 2 females and 2 males? This video explains the counting principle and how to determine the number of ways multiple independent events can occur.

Random Experiment : An experiment in which all possible outcomes are know and the exact output cannot be predicted in advance, is called a random experiment. A dice is a solid cube, having 6 faces, marked 1, 2, 3, 4, 5, 6 respectively. When we throw a die, the outcome is the number that appears on its upper face. There are 4 honours of each unit. There are Kings, Queens and Jacks. These are all called face cards.
