If a coin is tossed twice, what is the probability that one of the flips was heads and one of the flips was tails?	Choose one:	A) 1/2	B) 1/8	C) 1/4	D) 1/6	E) 3/4
The possible cases are =&gt;{Head,Head} {Head,Tail} {Tail,Head} {Tail,Tail}   Possible Cases=4   Favourable cases = 2   P(E) = 2/4 = 1/2   1/2nswer: 1/2
