10. Three coins are flipped 150 times. What is the approximate probability that you flip 3...
three coins are flipped 32 times. over these 32 trials, how many times would you expect to flip two heads and one tails.
When a coin is flipped 3 times, what is the Probability that you get at least one Heads? TIP: Write out all the possible sequence outcomes of what can happen when you flip a coin 3 times and think about what the 'at least one' means to us here. O 1/2 or 0.5 3/4 or 0.75 O 7/8 or 0.875 8/8 or 1
Problem 4. Five coins are flipped. The first four coins will land on heads with probability 1/4. The fifth coin is a fair coin. Assume that the results of the flips are independent. Let X be the total number of heads that result Hint: Condition on the last flip. (a) Find P(X2) (b) Determine E[X] S.20
13. What is the probability for exactly three of five flipped coins to land heads, and in how many different ways can they land to give this result?
A box contains four coins. Three of the coins are fair, but one of them is biased, with P(11) = ? (where 11 is the event of flipping heads). You take a coin from the box and flip it. It comes up heads. What is the probability that you have flipped the biased coin?
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
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...
A coin is flipped three times. What is the probability that the first and last flips are heads?
A coin that comes up heads with probability p is flipped n consecutive times. What is the probability that starting with the first flip there are always more heads than tails that have appeared?
There are three coins. They have chances 0.4, 0.6 and 0.8 respectively of showing heads. One of these three coins is chosen at random and flipped. (a) What is the chance that the coin chosen is the coin with probability equal to .4 of showing heads and a head shows up after the flip? (b) What is the chance that the coin, when flipped, shows a head? (c) Given that the coin, when flipped, shows a head, what is the...
