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. Outcome Frequency Experimental Probability HHH 112 HHT 129 Collections: Mathematics
