Introduction to three types of probability:
Three types of probability article deals with the definition of three types of probability and the model problems related to it.
Types of probability:
The probability is classified in to
Probability as counting.
probability as geometry
Probability as algebra, are the three types and the explanation is given below
Three Types of Probability:
Probability as counting:
This probability is very simple and easy to understand. This is used to find the probability of number of times an event occurs. This probability is calculated by dividing the number of successive out come by the total number of outcomes.
Probability as counting =` (("number of sucessive outcome")/ ("total number of outcomes"))`
Probability as geometry:
This probability is suitable for one or more continuous variable. We can find the probability dividing the length of successive part by the length of total parts in the event.
Probability as geometry = `(("length of successive part")/ ("length of total part"))` .
Probability as algebra:
This is applicable to problems where we can find the enough relationship between two probabilities, at that time we can solve the problem algebraically.Having problem with 10 cbse sample papers keep reading my upcoming posts, i will try to help you.
Model Problems to three Types of Probability:
Problem 1: what is the probability of getting 5, when a dice is thrown?
Solution:
The sample space S = {1, 2, 3, 4, 5, 6}
n(S) = 6
Getting 5 = {5}
n (5)= 1
Probability of getting 5 = `(n (5))/(n(S))`
= `(1/6)`
Probability of getting 5 is `(1/6)` .
Problem 2:
The probability of getting mark in next test is x, which is likely, equal to three the marks he will not get.what is the probability of marks in next test.
Solution:
Getting mark in next test is x
Probability he will not get is 1-x
By given data:
x =2(1-x)
x= 2-2x
x+2x=2
3x =2
x=`2/3`
The probability of getting mark in next test is `2/3`
Problem 3:
John is working from 8am to 5pm, every 15minutes he will go out. What is the probability of going out from 4pm to 5pm?
Solution:
John goes out every 15 minutes.
Probability of going out from 4pm to 5pm = `(15minutes)/(60 minutes)`
= `(15/60)`
= `(1/4)`
Probability of going out from 4pm to 5pm is `(1/4)`
