=
Ω
X¿
[0, if ith toss is head
1, if ith toss is tail
}.
Let Dmn be the event of observing exactly m tails after the first n tosses (where m≤n).
a. Write D23 using the roster method.
b. Write each of the following events in terms of Dmn (and only the set operations:
complementation, union, or intersection):
E = event of observing at least two tails after four tosses
F = event of observing a tail on the first toss only
G = event of observing heads in all four tosses
c. Fill in the blanks with the correct mathematical symbols:
(1,0,0,1)
D44 D33
