% Correct:

1	For a Binomial distribution there must be a fixed number (n) of trials
	True	False
2	For a Binomial distribution the probability of success (p) can vary from trial to trial
	True	False
3	For a Binomial and a Poisson distribution the events must occur independently of each other
	True	False
4	A Binomial distribution is never symmetric
	True	False
5	A Poisson distribution can provide a good approximation to the Binomial distribution
	True	False
6	Trials in a Binomial distribution have only two outcomes: success or failure
	True	False
7	In a Poisson distribution, events can occur singly or at the same time
	True	False
8	In a Poisson distribution, events occur at a constant rate, given by the parameter l
	True	False
9	The number of heads and tails when spinning a coin is a good example of a Poisson distribution
	True	False
10	The number of cars passing a road junction in a five minute period is a good example of a Binomial distribution
	True	False
