11 Samacheer Kalvi Solutions for 12.5.19 is given in a real board in a hand written format. This would be useful for students to understand the solution in easy and simple manner. The grasping power increases by reading the solution in a notes format. Hence we have given all the solution in volume 2 in this board format. Please share with your friends if you find this format useful.
The concept of probability was created by two mathematicians from France.Credit goes to both of them for the creation of Probability.The concept was further extended by Laplace who in the 18th century created the Bayesian concept.There are events in the real world that can not be predicted.To take an intelligent guess we have to define the probability of the event.
It is beneficial for students to understand the concepts of Probability as it will be applied in their career in the future when they work for corporations or government agenciesThe probability will be used to make business decisionsIt is always a good idea to make decisions using a mathematical formula instead of relying on experience or chance.There are always surprises in the events that happen around us.There could be many different outcomes of an event.
Determining the most likely outcome can be done with the help of the probability.If the result of the process is already known and can be defined it's an experiment.The experiment is called a Deterministic Experiment if one can predict the outcome of the experiment before it happens.Non-Deterministic Experiment is a name for Random experiment.We know the possible outcomes of a random experiment but we don't know which of them will happen.
sample space is the collection of all the possible outcomes of a random event.A countable number of sample points and an un countable number of sample points are the types of sample points in a sample space.It's not possible to divide the number of sample points into subcategories.Either an infinite number of sample points or a finite number of sample points can be used to describe the countable number of sample points.First we need to know the definition of probability and then we need to know about the following.
S is the sample space's owner.The number of elements in sample space isn't important.The sample space when a coin is thrown is Head Tail.The sample space consists of 2 elements.When two coins are thrown at the same time the sample space is HH HT TH and TT
When 3 coins are thrown at the same time the sample space is HHH HHT HTH HT TTH TTT and THH.Some elements are in the sample space.The two coins are the same as the one that was thrown two times.That's why we shouldn't get confused with them.One coin tossed three times can be called one coin thrown three times.
The sample space is 1 2 3 4 6 when there is a die.The number is 6.When two dies are thrown the sample space is 11 12 13 14 15 16 21 22 23 24 25 26 31 32 33 34 35 36 41 42 43 44 45 46 51 52 53It is 6 elements in the sample space.The number of sample spaces in coins can be found using the formula 2n.
The sample space size is 4 if we use the n as a reference number.The sample space size is between 8 and 16 if we put the n as 3 or 4.6n is the formula to find the number of dies that have sample spaces.The sample space size is 6 if we put n 2.The sample size is 36 if we put the n as a 2.
