Express all probabilities as fractions. A Social Security number consists of nine digits in a particular order, and repetition of digits is allowed. After seeing the last four digits printed on a receipt, if you randomly select the other digits, what is the probability of getting the correct Social Security number of the person who was given the receipt?

In this problem solving party first so the number of social security number can be given by late X is equal to 10 c one multiplication 10 c one multiplication Dancy one Multiplication 10 c one Multiplication Dancy one Multiplication 10 c one Multiplication 10 c one multiplication. 10 See one non solving it I get the value Age just located carefully 10 Multiplication 10 Multiplication 10 10 Multiplication 10 Multiplication 10 10 Multiplication 10 Multiplication 10 on solving it I get the final answer is one triple zero Triple zero, triple zero. So this is the answer of part one that the Social Security number can be for me now going to part B so part for part B let physical to guessing correctly the Social Security number of the president of the U. S. So it is given by one by 10 to the power nine minus one which is equal to zero point eight times 010203040506070801 So this is our answer for part B

Hello. Welcome to this lesson. In this lesson we'll find the ability of getting the President Social Security number. Now. There are nine they get so nine they get don't be. So the strand for the Social security number. Um You're selecting the each day begins comes from A Roll of 10. That is from joe to night. Okay So this also comes from 0 to 9. If a six it comes from 0 to 9. Fs 70 comes from 0 to 9. So a number of ways of getting or the Social Security numbers we have 10 times 10. That is 10 for each times 10 for each of the day gets and then I help them. So you have 1 to 34 56 seven eight line. So this keeps us. Yeah We have 99 zeros. That is nice zeros. Okay so. Oh. Mhm. Yeah. So the the number of ways that you can choose the president or just one out of this hole number that we have. Yes. What? So there a billion weeks four minutes. But you have just one out of a billion for the president. Okay. Right so that means that the probability of choosing the president's number With me quote. Just the one oh out of ah Cool. Lots that we have. Okay. Okay. Okay so thanks for time. This is the end of the lesson

This question, we are told about nine digits social security numbers and we're told that they were assigned at random. And if we randomly select a number, what is the probability that it belongs to one of 300 million people in the United States? million people in the United States? So basically we're just picking one Out of 300 00000. So 300 going through. Yeah, that's true. one over that is basically point three Times 10 to the negative 2, 3, 4, 5, 6, 7, 8 or three times 10 to the -9.

In this exercise, we are asked to consider the nine digit Social Security numbers assigned at random. And if we randomly select a number, what is the probability that it will be one of the 300 million people? The United States is numbers. Now for each of the nine digits, There are 10 ways to select it numbers zero through 9. And since there are nine digits, the total Number of permutations or the social security number is 10 to the exponent nine. So that is the size of our sample space. Now, if we randomly select one number, the number of americans for which it could match. I've called that end of a is 300 million Which is three times 10 to the eight. So that means out of the 10 to the nine possible social security numbers, 300 million of them would match an american citizen. So what is the probability of that happening? So let's just call that event X. So this probability is the ratio of the number of events. That would be the success. That would be X divided by the size of the sample space. And this comes out to 0.3. So we have about a 30% chance Of a randomly selected nine digit number being the socialist cared number of an american
