"we will use set theory for the mathematical model of events.outcomes of an experiment are elements of some sample space S,and each event is a subset of S.two events both occur if the outcome is in the intersection of two sets.at least one of a collection of events occurs if the outcome is the union "
"a box contains 100 balls,of which r are red.suppose that the balls are drawn from the box one at a time,at random,without replacement.determine(a) the probability that the first ball drawn will be red;(b)the probability that the 50th ball drawn will be red;(c)the prbability that the last ball drawn "
"9.if n people are seated in a random manner in a row containing 2n seats,what is the probability that no people will occupy adjacent seats?"
"Let Pn be the proportion of patients who don’t relapse out of the first n. It can be shown that the probability is 1 that Pn converges to something as n → ∞. That something can be thought of as P , which we have been calling the proportion of successes in a very large population. In this sense, P is"
"Suppose that the number of potential patients is enough larger than any sam- ple that we will see to make the approximation in Theorem 5.3.4 applicable. Then P is just the proportion of successes among the large population of potential pa- tients. Conditional on P = p, the number of successes in a s"
"The interesting probabilistic properties of δ can be summarized by computing, for each value of θ∈Ω, either the probability π(θ|δ) that the test δ will reject H₀...."
