 
Summary: Section 2.3 Introduction to Probability
1. Sample Space/Events: A coin is flipped, and it is noted whether
heads or tails show. Then a die is rolled, and the number on the
top face is noted. What is the sample space of this experiment?
Indicate the outcomes of the event "the coin shows tails and the die
shows at least 3".
2. Sample Space/Events: An urn holds 10 identical balls except that 1
is white, 4 are blue, and 5 are red. An experiment consists of select
ing two balls consecutively from the urn without replacement and
observing their color. What is the sample space of this experiment?
Indicate the outcomes of the event "neither ball is white".
3. Sample Space/Events: An executive must form an ad hoc committee
of 3 people from a group of 5, {A, B, C, D, E}. What is the sample
space? Indicate the outcomes of the event "D is selected".
4. Experimental Probability: An experiment requires 3 coins to be
flipped 1000 times. The results are recorded in the following table;
fill in the third column.
