A person tosses two coins

a) Is the following probability assignment consistent: Pr(HH)=0.3, Pr(HT) = Pr (TH) = 0.2. Pr(TT) =0.3

b) Is either coin fair ( i.e. is the propability of obtainig tail on either coin equal to 0.5) ?

c) Are the coins independent ?

Flip 2 fair coins. Then the sample space is {HH, HT, TH, TT} where T = tails and H = heads. The outcomes HT & TH are different & the HT means that the first coin showed heads and the second coin showed tails. The TH means that the first coin showed tails and the second coin showed heads. Let A = the event of getting at most one tail. What is the probability of event A?

Suppose that we have a box that contains two coins: A fair coin: ?(?)=?(?)=0.5 . A two-headed coin: ?(?)=1 . A coin is chosen at random from the box, i.e. either coin is chosen with probability 1/2 , and tossed twice. Conditioned on the identity of the coin, the two tosses are independent. Define the following events: Event ? : first coin toss is ? . Event ? : second coin toss is ? . Event ? : two coin...
