A committee of 4 is to be selected from a group of 12 people. How many possible different committees can be selected?
expected value
A measure of the average value of a random variable is called a(n)
binomial probability distribution
A probability distribution showing the probability of x successes in n trials, where the probability of success does not change from trial to trial, is termed a
discrete random variable
A random variable that can assume only a finite number of values is referred to as a(n)
50
Assume that you have a binomial experiment with p = 0.5 and a sample size of 100. The expected value of this distribution is
9
Assume your favorite soccer team has 2 games left to finish the season. The outcome of each game can be win, lose or tie. The number of possible outcomes is
the posterior probabilities
Bayes' theorem is used to compute
combination
The counting rule that is used for counting the number of experimental outcomes when n objects are selected from a set of N objects where order of selection is not important is called
the probability of success changes from trial to trial
The key difference between the binomial and hypergeometric distribution is that with the hypergeometric distribution
a discrete random variable
The number of customers that enter a store during one day is an example of
zero to one
The range of probability is
1.0
The sum of the probabilities of two complementary events is
0.38
If A and B are independent events with P(A) = 0.38 and P(B) = 0.55, then P(A given B) =
.80
If P(A) = 0.50, P(B) = 0.60, and P(A intersection B) = 0.30, then P(A union B) =
must always be equal to 0
If two events, A and B, are mutually exclusive, the probability of A intersection B
Poisson distribution
In the textile industry, a manufacturer is interested in the number of blemishes or flaws occurring in each 100 feet of material. The probability distribution that has the greatest chance of applying to this situation is the
a continuous random variable
The weight of an object is an example of
