100n 80 7 87 100n subtracting these two numbers we get after solving we get 693 99n the digit can be arranged in 3 ways or 6 ways we have already investigated 2 of these ways we can now try one of the remaining 4 ways one of these are n 95 100n 70 8 693 99n 199n 615 after solving we get n=3 answer :the unknown digit is 3.

theoretical probability 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 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 the die is so constructed that the event numbers are twice as likely to occur as the odd numbers read more on what is a parallelogram

let us find the probability of b given a where a is the event getting a number greater than 3 while tossing the die s {1 2 3 4 5 6 if probability of getting an odd number is x the probability of getting an even number is 2x.
