Ex: The probability of randomly guessing correctly at a multiple choice question is .2. If Sally guesses at all 20 questions, what is the probability that she will get at least 6 correct. Ans: 1 – binomcdf (20, .2, 5). 6. geometpdf (p, X): In the geometric setting this gives you the probability …

The listing of all possible outcomes is called the sample space of the random process. A probability model describes all possible outcomes and assigns probabilities to them. In some cases it is reasonable to assume that the sample space outcomes are equally likely. (This is sometimes called the classical approach to probability.)

The probability that you will answer exactly 4 correct is B(24, 0.2, 4) = 0.196. At least 20 correct = 20 correct + 21 correct + 22 correct + 23 correct + 24 correct = . It is easy to use calculator with binomcdf as follows: At most three wrong: At most three correct: Example 5. A computer manufacturer tests a random sample of 28 computers.

Find the probability that in a random sample of 13 Americans, the number who will say they have gained “a lot” of weights in the past five year is at most 2. (8 points) Two fair dice are rolled. Find the probability that the sum is 8 or 11. Find the probability that the sum is 6, given that one of the dice shows an odd number. (12 pts: 4 ea.)

So the number that agree is a random variable X having the binomial distribution with n = 2500 and p = 0.16. To find the probability that at least 1520 of the people in the sample find shopping frustrating, we must add the binomial probabilities of all outcomes from X = 1520 to X = 2500. This isn’t practical. a.
