Consider the following. (a) Draw a tree diagram to display all the possible head-tail sequences that can occur when you flip a coin three times (b) How many sequences contain exactly two heads?(c)...

(a) Draw a tree diagram to display all the possible head-tail sequences that can occur when you flip a coin three times




(b) How many sequences contain exactly two heads?




(c)
Probability extension:
Assuming the sequences are all equally likely, what is the probability that you will get exactly two heads when you toss a coin three times? (Round your answer to three decimal places.)
