In this video we are discussing sample
spaces and probability of basic concept

00:06.900 --> 00:15.500
So, a probability experiment is a chance
process that leads to well-defined results and

00:15.500 --> 00:24.280
also known as the outcomes. An outcome is the result
of a single trial of a probability experiment

00:24.280 --> 00:29.720
So whenever we execute one probability
experiment, we are going to get one outcome

00:30.000 --> 00:37.000
A sample space is a set up all possible
outcomes of a probability experiment

00:37.000 --> 00:45.220
So in a probability experiment we might be having several
outcomes. So set up all these outcomes will form one sample space

00:45.220 --> 00:55.260
Let us show you some examples. So to toys one coin if it is
the respective experiment, then the outcome sample space will

00:55.260 --> 01:03.880
be head and tell. a die, 1, 2, 3, 4, 5, 6 is
the outcome space, that is a sample space

01:03.880 --> 01:09.500
Answer a true or false question, here
the sample space is true or false

01:09.500 --> 01:17.780
Toss 2 coins, here the sample space is
head, head, head, tell, tell, and tell head

01:17.780 --> 01:24.260
So let us suppose another example. Find
out the sample space for rolling two dies

01:24.260 --> 01:31.580
In that case, you can consider a die 1. It has got a sample space
like this and if you consider dye 2, it has got a sample space

01:31.580 --> 01:39.940
like 1, 2, 3, 4, 5, 6. Now if you find the sample space
of rolling 2 dies in that case, this is the respective

01:39.940 --> 01:59.700
sample space for rolling two dies. So here we are having this 1 2 1 3 1 4 1 5 1 6 1 that means considering these values
and this and then we are having 1 4 5 6 In this way here we are having respectively 66 different values in the sample

01:59.700 --> 02:08.639
space. An event consists of a set of outcomes
of a probability experiment. An event can

02:08.639 --> 02:15.459
be one outcome or more than one outcome.
For example, if a die is rolled

02:15.640 --> 02:21.940
and a six shows, this result is called
outcome, will be known as the outcome

02:22.440 --> 02:29.739
Hence, and since it is a result of a single
trial, an event with the one outcome is known as

02:29.739 --> 02:35.000
the simple event. So, one event with the
one outcome is known as a simple event

02:35.760 --> 02:42.700
The event of getting an odd number when a
die is rolled is called a compound event

02:42.700 --> 02:50.739
since it consists of three possible outcomes or
three simple events because to get the odd number

02:50.739 --> 02:57.380
after rolling a die after rolling a die to get
a odd number here this is known as a compound

02:57.380 --> 03:06.019
event because it consists of three different
outcomes so that is one three and five in general

03:06.019 --> 03:11.880
a compound event consists of two
or more outcomes or simple events

03:12.700 --> 03:22.840
There are three basic interpretations of probability. So here three
basic interpretations of probability we are going for one by one

03:22.840 --> 03:29.820
One is a classical probability. Next one is an
empirical or relative frequency probability

03:29.820 --> 03:39.940
And last one is a subjective probability. So in the next three videos
we are going to discuss all these probabilities with some examples

03:39.940 --> 03:40.940
