Question

1/22/2019 M243-Ch.3 HW 29.-/12 points 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, 150 showed a head (event H) while 100 showed a talil (event T). On that basis, they claimed that it is not a fair coin. Part (a) Based on the given data, find P(H) and P(T). (Round your answers to two decimal places.) 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.) н,00000 TH, 0.2400 HT Part (c) Use the tree diagram to flnd the probability of obtaining exacty one head in two spins of the coln. (Round your answer to four decimal places.) Part (d) Use the tree diagram to find the probability of obtaining at least one head. (Round your answer to four decimal places.) Show My Work (Optional)

Please help me understand how to do a tree diagram. Thanks!
