suppose you flip a fair coin five times. which of these pairs of events are disjoint?
(a). you get five heads;you get four heads and a tail
(b). the first flip is a head;the second flip is a head
(c). you get five heads; the second flip is a tail
(d). you get three heads and two tails;the secon flip is a tail
(e). the first four flips are heads;the first three flips are heads
(F). the first head occurs on the third flip;the fourth flip is a head
(g). the first head occurs on the third flip; three of the flips are heads

Which events are mutually exclusive — they cannot occur at the same time?
I hope this helps you to make your decision.
