probability

Dear readers, I have a problem saying: "Let [X1, X2,....] be a sequence of random variables such that Xn is distributed according to a Bernoulli distribution with parameter (1/n), with n an integer number. Prove that Xn converges in probability to 0, by obtaining P(|Xn| > Epsolon). Could you...

In the final match a boxer is facing another boxer and is expected to win 48% of the time. In reality they win 80% of the time. What is the probability of that occurring in 10 matches? 2) In the very next match (in a different tournament), the boxer who won the previous match only wins 40% of...

Roll a dice five times. Record the results in Sample 1. Repeat the experiment for Sample 2, 3, and 4. In a live classroom setting, actual survey data is used. In this knowledge check online environment, please use the following data: Sample 1 Sample 2 Sample 3 Sample 4 2 4...

Hi :) I am new here on the forum and find it a bit difficult to learn the way to go at different statistics/probability - problems. For the most times I am able to figure it out myself doing some research, but the last two problems has got me stuck for a few days. I would be really thankful for...

Can anyone help me understand this? Consider the four observations from de Normal Distribution with variance equal to one y1 < 10, y2 > 10, 5 < y3 < 10 and y4 = 10. The likelihood function is? Would be: Replacing: I want to know if this is correct or have another way of solving this...

## LaTeX Code Can anyone help me understand this? Consider the four observations from de Normal Distribution with variance equal to one $y_1 < 10$$, y_2 > 10 $, $5 < y_3 < 10 $ and $ y_4 = 10$. The likelihood function is? Would be: $ \prod_{1}^{4} \frac{1}{\sqrt(2\pi)}\exp{-\frac{(y_i...

How many ways are there to categorize 12 people into 3 teams of 4? if order does not matter: 12!/4!4!4!3! or ((12 choose 4)(8 choose 4) (4 choose 4))/3! if order matters across teams: 12!/4!4!4! (or (12 choose 4) (8 choose 4) (4 choose 4)) Then, if order matters within teams or if order...

Dear All, Below is my question; You are a statistics insctructor and you cover the topic of logistic regression. In order to ensure that your students understand the material , you create a short quiz covering the material from the section. --Among the students who take the quiz, those who...

As the title say. I have made a linear regression analisy of an event, and I got the concentration of probabilities at a given space of the Graphic (X, Y) ... so how to extract the odds of the event to happen by this linear regression analisy? This is the grahic:

Hi everyone - see my problem below. With a regular die I know my denominator is 36 for each probability. What I'm wondering here is if that changes since multiple sides of the die have the same number... Right now I have the probability of a sum of 2 is 1/36, a sum of 3 as 2/36, sum of 4 as...

So this is a bit confusing and I will try to explain the best way possible: 1 parent 1 parent = 2 Parents + + = No + - = No - +...

What is the best statistical method to measure the probability of people fitting a certain criteria in my data overlapping with another criteria? I am tasked to display this in a column/bar chart for a simple display of the consequence of its selection on other relevant pots of data.

I need a hlep because i didnt understand the course so If someone can help me for thi thank you very much

A slot machine works on inserting a $1 coin. If the player wins, the coin is returned with an additional $1 coin, otherwise the original coin is lost. The probability of winning is 1/2 unless the previous play has resulted in a win, in which case the probability is p < 1/2. If the cost of...

does anyone understand this question? Thanks in advance!

I am not really sure how to calculate question C. Can anyone help me out? Thanks in advance!

Alright, I have been working on my statistics assignment since Monday and I only have two questions left, dealing with the probability of a sampling error. Unfortunately, I cannot find anything in my notes and only a brief example in my textbook that does not explain the concepts behind the...

Hi everyone! I have a question about the answer of question 19a and e. question a: Find the probability that X is greater than 60. Why do they do 0,5 -0,3944 and not 1 - ...? Question e was: the probability is 0,05 that X is in the symmetric interval about the mean between which two numbers...

Hello everyone, I don't really understand the answer of question a. The question was: Find the probability that on any given day there will be fewer than two breakdowns on this highwayduring the morning rush hour. Additional information: on average: 3,2 breakdowns per day occur. isn't it...

I have read two defintions for a random variable. 1. It is a function from the set of all posisible outcomes to the real line. For example Y("male")=0 2. A variable where known probabilities are associated with sample outcomes. Which one is correct? Defintion 1 does not include a probability...
