An experiment is to flip a coin until a head appears for the first time. Assume the coin may be biased, i.e., assume that the probability the coin turns up heads on a flip is a constant p (0 < p < 1). Let X be the random variable that counts the number of flips needed to see the first head. (a) Let k ≥ 1 be an integer. Compute the probability mass function (pmf) p(k) = P(X = k)....

As a binomial question: Flip a coin twice. The probability of observing a head is 50%, what is the probability that I observe 1 head? binompdf (n, p, x) so binompdf( 2, .50,1) Sampling Proportion question (8.2): There is a 50% of observing a head. If we flip the coin 100 times, what is that at most 30% of the flips will be heads? n*p*(1-p) =100*.50*.50=25 (Do not use my coin example. Use your own scenario). pˆ=.30 po or μ=50...

I flip a fair coin and recorded the result. If it is head, I then roll a 6-sided die: otherwise, I roll a 4-sided die and record the results. Let event A be the die has a 3 or greater. let event B be I flip tails. (a)-List all the outcomes in the Sample space (b)- List the outcomes in Event A and B (c)- List the outcomes in A or not B (d)- Calculate the probability of event A...

You flip a coin 100 times to see whether it is biased and get 60 heads. Explain two different ways you could find the p-value of this experiment.

Your unfair coin comes up heads with probability 0.6. You flip it until you get four heads in a row. Let t be the expected number of times you flip. Write an equation for t. (Your equation, if solved, should give the value of t).

1. A) If you flip an unfair coin 100 times, and the probability for a coin to be heads is 0.4, then the number of heads you expect on average is: B) If you flip an unfair coin 100 times, and the probability for a coin to be heads is 0.4, then the standard deviation for the number of heads is: C) If you flip an unfair coin 2 times, and the probability for a coin to be heads is...

Suppose that you flip a coin 11 times. What is the probability that you achieve at least 4 tails? A sign on the pumps at a gas station encourages customers to have their oil checked, and claims that one out of 5 cars needs to have oil added. If this is true, what is the probability of each of the following: A. One out of the next four cars needs oil. Probability = B. Two out of the next eight...

A perfectly balanced coin is tossed, there is equal chance to get a head (H) or a tail (T ). Consider a random experiment of throwing SEVEN perfectly balanced and identical coins. Let S denote the sample space. a) List the elements in S. (b) Find the probability that there is three tails and four heads.

Would you flip a coin for the chance of winning two dollars? What if you were...

Would you flip a coin for the chance of winning two dollars? What if you were given a dollar and offered the chance to flip a coin to either gain a second dollar or lose the first? Which wager seems more appealing—the first or the second? Far more people choose the first wager than the second. Both scenarios have exactly the same probability of outcomes: a 50% chance of ending up with nothing, and a 50% chance of ending up...

You flip a coin, if it is heads you will have a good day and if it is tails you will have a bad day. There are 30 days in total. (a) What is the expectation and variance of the number of times you will have a good day throughout this 30 day stretch? (b) What is the probability that every day will be bad for all of the 30 days?
