A wedding reception has exactly 2n guests. There are n children and n adults. Each guest writes the name of their preferred dance partners on a piece of paper (allowed more than one!). A couple will dance together if and only if they each chose the other person as their preferred dance partner. For example, if Carol wants to dance with Bob and Bob

A computer manufacturer estimates that its line of minicomputers has, on average,8.5days of downtime per year. To test this claim, an analyst contacts seven companies that own one of these computers and is allowed to access company computer records. It is determined that, for the sample, the average number of downtime days is5.7, with a sample

Guidance Missile System A missile guidance system has five fail-safe components. The probability of each failing is 0.2. Assume the variable is binomial. Find the following probabilities. Do not round intermediate values. Round the final answer to three decimal places. Part 1 of 4 (a) Exactly three will fail. P(exactly three will fail) = 0.10

I. According to the Mendelian theory of inherited characteristics, a cross fertilization of related species white-flowered plants produces a generation whose offspring contain 25% red-flowered plants. Suppose that a horticulturist wishes to cross 5 pairs of the cross-fertilized species. Of the resulting 5 offspring, what is the probability that a)
