When the Euro coin was introduced in 2002, two math professors had their statistics students test whether the Belgian one Euro coin was a fair coin. They spun the coin rather than tossing it and found that out of 250 spins, 160 showed a head (event H) while 90 showed a tail (event T). On that basis, they claimed that it is not a fair coin. O Part (a) Based on the given data, find P(H) and P(T). (Round your answers to two decimal places.) P(H) = 0.6 P(T) = 0.4 O Part (b) Use a tree diagram to find the probabilities of each possible outcome for the experiment of spinning the coin twice. (Round your answers to four decimal places.) H. Н. 0.6400 TT TH, d.2304 HT H O Part (c) Use the tree diagram to find the probability of obtaining exactly one head in two spins of the coin. (Round your answer to four decimal places.)
