A fair quarter is flipped three times. For each of the following probabilities, use the formula for the binomial distribution and a calculator to compute the requested probability. Next, look up the probability in the binomial probability distribution table. (Enter your answers to three decimal places.)
(a) Find the probability of getting exactly three heads.
(b) Find the probability of getting exactly two heads.
(c) Find the probability of getting two or more heads.
(d) Find the probability of getting exactly three tails.
You can look up the probability from this binomial probability distrubution table,
first search value of n
then go to value of x on column and value of p on row.

A fair quarter is flipped 4 times. For each of the following probabilities, use the binomial distribution table to compute the requested probability. a.) Find the probability of getting exactly 2 tails. b.) Find the probability of getting three or more tails. c.) Find the probability of getting no heads. d.) Find the probability of getting exactly 1 head. e.) Find the probability of getting exactly 4 tails
Answer part a and part b please!!! (a) What is the conditional probability that exactly four Tails appear w when a fair coin is flipped six times, given that the first flip came up Heads? (I.e. the coin , then is flipped five more times with Tails appearing exactly lour times.) (b) What if the coin is biased so that the probability of landing Heads is 1/3? (Hint: The binomial distribution might be helpful here.) (a) What is the conditional...
Consider a game in which a coin will be flipped three times. For each heads you will be paid $100. Assume that the coin comes up heads with probability 1/3. a. Construct a table of the possibilities and probabilities in this game. Probability Outcome Possibilities 0 heads, 3 tails / 1 heads, 2 tails 2 2 heads, 1 tails 3 3 heads, 0 tails b. Compute the expected value of the game. The expected value of the game is $...

1. A fair coin is flipped four times. Find the probability that exactly two of the flips will turn up as heads. 2. A fair coin is flipped four times. Find the probability that at least two of the flips will turn up as heads. 3. A six-sided dice is rolled twice. Find the probability that the larger of the two rolls was equal to 3. 4. A six-sided dice is rolled twice. Find the probability that the larger of...
TEAFM2 4.6.024 A fair coin is flipped four times. least three times? What is the probability that heads occurs exactly 3 times if it is known that heads occurs at
2. A coin is altered so that the p coin is flipped three times as altered so that the probability of getting a head on every flip is 0.6. Suppose this (*) is flipping the coin a binomial experiment? Explain by checking if the four properties of binomial experiments are satisfied. (b) What is the probability that there are at least two heads? (c) What is the probability that an odd number of heads turn out in 3 flips? (d)...
A fair coin is flipped 20 times. a. Determine the probability that the coin comes up tails exactly 15 times. b. Find the probability that the coin comes up tails at least 15 times. c. Find the mean and standard deviation for the random variable X giving the number of tails in this coin flipping problem.
Assume a fair coin is flipped 3 times. Probability of getting heads is .5..Use the normal approximation method (and relevant standard normal table) to solve by hand for the probability of obtaining 2 or more successes of getting heads in this situation. Show your work.
of a fair coin. Also use the binomial formula and compare the two probabilities. For the normal approximation use z (x-H)/a, then use the tables, and for the binomial use (n C x) "(1-0) . Given heads is a success when we flip a coin, a six when we roll a die, and getting an ace when we select a card from a 52-card deck. Find the mean and std. deviation of the total number of successes when we (a)...
