In V Grade of cbse board, we are going to get Introduction to Probability,
Basically probability means the possibilities of the occurance of a particular event and its possible outcomes.
Let us first see what an experiment is ?(want to know more about experiment then refer to online math tutor available on Internet)
An experiment which can produce some well defined outcomes is called an experiment.
All the Outcomes of an experiment are called events
Suppose we are making predictions for if it will rain or not: then there are two possible outcomes,
1. It may rain
2. It may not rain
In probability we talk about any event that occurs in the universe and on that particular event. The process of making predictions takes place and the possible outcomes are taken into considerations.
Let us consider an event of a child going to school on Monday, the possible outcomes are
1. He may come to school.
2. He may not come to school.
This is called probability.
We use probability in our daily life. We usually find the events occuring in our life, sometimes we speak some sentences like:
Most probably my grandmother will come tomorrow.
I doubt that if you will pass this time.
There are high chances that we will reach in the finals of the tournaments. All these words explain about the possibilities of the any event to occur.
Suppose we take any event of throwing a coin. The possible outcomes are Head (H) and Tail (T)
After throwing the coin either Head or Tail will be appearing.
So probability of getting a head P(H) = 1 out of 2.
p(H) = 1/2
The chances are that either the Head or Tail will appear as one of the outcome.
If two coins are thrown at random, then the possibilities of the outcomes are HH, HT, TH, TT
If we throw a dice we observe that one of the possible outcomes are 1, 2, 3, 4, 5, 6. It means that when the dice is thrown, one of these outcomes will appear. So these are called the probability of occurrence of any event.
The possibility of getting a number 1 = 1 out of 6 => p(1) = 1/6
The possibility of getting a number 2 = 1 out of 6 => p(2) = 1/6
The possibility of getting a number 3 = 1 out of 6 => p(3) = 1/6
The possibility of getting a number 4 = 1 out of 6 => p(4) = 1/6
The possibility of getting a number 5 = 1 out of 6 => p(5) = 1/6
The possibility of getting a number 6 = 1 out of 6 => p(6) = 1/6(To know more about probability click here)
We study probability in all aspects of life.
If we put 10 marbles in a box, out of which 5 are red in color, 3 are blue in color and 2 are green. If we have to take out one marble out of the box, what is the probability of 1getting a red marble = P (red) = 5/10
2) getting a blue marble = P(Blue) = 3/10
3) getting a green marble = P (green ) = 2/10
So this is the way we study Steps in problem solving for probability . I hope that what I have told is sufficient for you and to know about 4th Grade Probability and Statistics you can refer to Internet.
