... A polling organization has a list of 1,000 people for a telephone survey. The pollsters know that 433 people out of the 1,000 are members of the Democratic Party. Assuming that a person cannot be called more than once, what is the probability that the first two people called will be members of the ...

... we can show that. Since Ω and ∅ are disjoint (the empty set is disjoint from every set), therefore P (Ω ∪ ∅) = P (Ω) + P (∅). But Ω ∪ ∅ = Ω, so 1 = 1 + P (∅). Thus, P (∅) = 0. We’ll prove the following theorem in class with the help of Venn diagrams to give us direction. Theorem. Let Ω be a sample s ...

Introduction to Probability
... Equally-likely Approach: If an experiment must result in n equally likely outcomes, then each possible outcome must have probability 1/n of occurring. Examples: 1. Roll a fair die 2. Select a SRS of size 2 from a population Subjective Probability: A number between 0 and 1 that reflects a person’s de ...
