This can be calculated using the binomial probability formula: P(X=k) = C(n, k) * p^k * (1-p)^(n-k) where n is the number of trials (tosses), k is the number of successful outcomes (tails), p is the probability of success (0.5 for a fair coin), and C(n, k) is Show more…

6. Calculate the probability for each of the following: a. Two tails in two tosses of a fair coin. b. Three heads in three tosses of a fair coin. c. Four heads in four tosses of an unfair coin where the probability of a head is 0.75. d. Three sixes in three rolls of a fair die. e. Five fours in five rolls of an unfair die where the probability of a four is 0.25.

Suppose you just received a shipment of twelve televisions. Three of the televisions are defective. If two televisions are randomly selected, compute the probability that both televisions work. What is the probability that at least one of the two televisions does not work? The probability that both televisions work is 0.545 (Round to three decimal places as needed). The probability that at least one of the two televisions does not work is 0.455 (Round to three decimal places as needed).

A biased coin is flipped 10 times. In a single flip of the coin, the probability of heads is 1/4 and the probability of tails is 3/4. The outcomes of the coin flips are mutually independent. What is the probability of each event? (a) Every flip comes up heads. (b) The first 5 flips come up heads, and the last 5 flips come up tails. (c) The first flip comes up heads, and the rest of the flips come up tails.
