The numeric value representing the chance that a particular event will occur is referred to as __________.
area of opportunity
The basic elements of probability theory are the individual __________ of a process due to a particular event.
____________ approach to assigning probability always assumes that all elementary events are equally likely to occur.
If two events
are __________, then the probability that both event
will occur is equal to the product of their respective probabilities.
The weighted average over all possible outcomes for a discrete variable is also called the __________.
A ______________ for a discrete random variable is a complete set of all possible distinct outcomes and their probabilities of occurring.
Choose the following property that is
essential to the binomial distribution.
The outcome on a particular trial is independent of the outcome on any other trial.
Each elementary event is classified into one of two mutually exclusive and collectively exhaustive categories.
The probability of an outcome being classified as success,
, is constant from trial to trial.
None of the choices are correct.
The __________ of a binomial distribution is the product of its two parameters,
The probability that the
th success occurs on the
th trial, in case that there is a constant probability of success,
, is determined using a _____________ distribution.
If one out of every 25 students is expected to fail an exam, determine the probability that a professor grading exams from a class of 100, will give the first exam a failing grade.
A researcher has found that the number of defective parts produced for a given process follows a Poisson distribution with a mean of 5.8 defective parts per hour. Give the standard deviation for the number of defective parts for this process.
A chemical engineer is trying to electroplate copper onto a circuit board. The engineer has found that the probability that a plating will be successful follows a geometric distribution and has a mean of 12. Determine the standard deviation for this process.
A box contains the following geodes, 4 hemalites, 5 tiger eyes, and 3 smoky quartz. If 3 geodes are removed, what is the probability that exactly two will be smoky quartz? (Use the formula for the hypergeometric distribution.)
A hypergeometric distribution has a mean of 15 when the sample size is 30 and the population size is 100. Determine the standard deviation for the distribution.
If two events are _________, they cannot occur at the same time.
