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.
18. A fair coin is flipped multiple times until it lands on heads. If the probability of landing on ( point) heads is 50%, what is the probability of first landing on heads on the fourth attempt? 00.625 0.500 00.412 00.382
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.
3. A fair coin is flipped eight times and the number of heads is counted. Calculate the probability that the coin will land heads more than 6 times. 4. A coin is flipped 8 times. Calculate the mean, variance and standard deviation
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...
