Their responses are as follows: 20% strongly agree: 13% agree: 12% neutral; 50% disagree; 5%6 strongly disagree. What isthe chance of a random person responding with strongly agree' given that he/she is not neutral? Round off your answer to twodecimal places.Answer is Blank 1

The below was the answer I received when I asked the following question. Dr. Deming’s Red Bead Experiment is an exercise in the laws of probability. The workers were frustrated because no matter what they did, the outcome was not predictable. If the paddle holds 50 beads and there are 500 white beads and 50 red beads in the box, what is the probability, using one sample, of filling a paddle with 47 white beads and only three red beads? What I need to understand is how did you get the highlighed answers below because these require a factorial of 500 and I have not found anything that will calculate that. Thank you Step 1 Given Information: Number of white beads = 500 Number of red beads = 50 Total number of beads = 550 Step 2 The probability, using one sample, of filling a paddle with 47 white beads and only three red beads can be determined as follows: Probability = C47500*C350C50550=(2.94*10^66) (19600)(3.44*10^71)=0.1675
You are to submit 2 real life examples of statistical statements and state if they are biased or unbiased Example: A toothpaste advertisement states that 3 or 4 people prefer their product. This could be a biased survey, one that is not based on a random sample. They could have asked exactly 4 people about their product. An unbiased sample accurately represents the population. Each member of the population is equally to be chosen Example: A person wants to find out how many people prefer chocolate of vanilla ice cream. To get an unbiased sample, she would pick out a few of the ice cream shops in her town and survey people leaving the establishment.
Q.3 (i) You are taking a 50 question multiple choice test. Each question has 4 choices. Clueless on 1 question, you decide to guess. What is the probability that you will get it correct? (ii) If a passing grade is 30 correct answers, what is the probability that you will pass if you guess on all 50 questions.
Maria plays basketball and is a 64% free throw shooter (meaning on average she hits 64 of 100 free throws). Maria attempts five free throw shots in a typical game. During a 25-game season, Maria had a game in which she attempted five free throws and hit all five of them. Do you think she had a "hot" day, or was it just chance? Explain your reasoning. .……... Is the streak surprising? Explain. Select the correct choice below and fill in the answer box(es) within your choice. (Round to two decimal places as needed.) A. The probability that she made five free throw tosses out of five is OB. The probability that she made five free throw tosses out of five is OC. The probability that she made five free throw tosses out of five is D. The probability that she made five free throw tosses out of five is which makes it very surprising. and the probability of it happening at least once in the season is which is very unlikely regardless of the number of games in the season. which is likely to…
I will be glad if the answer comes quickly
