probability and statistics when we are solving conditional probability examples ,we deal with two events say a and b sometimes these events are so related to each other that the probability will depend on whether the other event has already occurred conditional probability can be defined as the probability of an event given that another event has already occurred let s consider an example for conditional probability consider a card game suppose a player needs to draw 2 cards of the same suit to win out of 52 cards there can be 13 cards in each suit if the first player draws a heart and the player wishes to draw a second heart if one heart has already been chosen then we only have 12 hearts remaining out of 51 cards so the conditional probability p 12/51 know more about formula for slope

let us consider the random experiment of throwing a die let a be the event of getting an odd number on the die let b {2 3 4 5 6 if after the die is thrown we are given the information that the event b has occurred then the probability of event a will no more be 1/2 because in this case the favourable cases are two and the total number of possible outcomes will be five and not six the probability of event a with the condition that event b has happened will 2/5 this conditional probability is denoted as pa/b let us define the concept of conditional probability in a formal manner let a and b be any two events associated with a random experiment the probability of occurrence of event a when the event b has already occurred is called the conditional probability of a when b is given and is denoted as pa/b the conditional probability pa/b is meaningful so far we have assumed that the elementary events are equally likely and we have used the corresponding definition of probability however the same definition of conditional probability can also be used when the elementary events are not equally likely this will be clear from the following example suppose a die is tossed let b be the event of getting a perfect square learn more on what is the slope formula

the die is so constructed that the event numbers are twice as likely to occur as the odd numbers let us find the probability of b given a where a is the event getting a number greater than 3 while tossing the die conditional probability examples example 1 a card is drawn from an ordinary deck and we are told that it is red what is the probability that the card is greater than 2 but less than 9 solution let a be the event of getting a card greater than 2 but less than 9 b be the event of getting a red card we have to find the probability of a given that b has occurred that is we have to find p a/b in a deck of cards there are 26 red cards and 26 black cards nb 26 among the red cards the number of outcomes which are favourable

solving math problems is not easy a lot of students have difficulty with math questions but employing some of these techniques will help you to solve math problems easily the following steps are generally followed to solve math problems read it carefully math problem solving involves reading the problem slowly and carefully in order to understand what is to be solved at times you miss out important information when you give it a quick reading break the problem into parts before solving a problem it is important to break it down into parts clearly define what you need to do what all information has been given in the problem and what you already know once you have that written down it gets easier to solve the math problem online change it into an equation it is important to convert what you read in words into an equation you can solve so basically you need to change the english into numbers always cross check once you get the answer to your math problem you should always go back and recheck sometimes you might miss out on small details and going over the problem and solution again helps read more on formula to find slope

ask until it gets clear math is all about concepts so it is important to understand the process of how to solve a math problem until you get around to doing it it is important to ask questions and get clarity on the concept once a new topic is introduced you should write it down review it and in case of any doubts bring it up with your tutor this process of continuously revising what you learn will gear you up to solve math problems online help with math topics tutorvista s expert tutors will make solving problems very easy our expert tutors will work with you in a personalized one-on-one environment to help you understand math questions better thereby ensuring that you are able to solve the problems.

Finding Arc Length

We know that if f(x) is a function and if the line ax + by + c = 0 meets the curve only at infinity, then the line ax + by + c = 0 is called an asymptote. Horizontal asymptote: It is an asymptote which is horizontal. The asymptote is thus parallel to x
