You should be given p(x) values such as 0.09 0.19 0.14 0.29 you just add these values to get 0.71 subtract 0.71 from 1 to get 0.29 is the answer

The Binomial Probability DistributionA binomial experiment is one that possesses the following properties:On this page...Mean and variance of a binomial distributionThe experiment consists of n repeated trials;Each trial results in an outcome that may be classified as a success or a failure (hence the name, binomial);The probability of a success, denoted by p, remains constant from trial to trial and repeated trials are independent.The number of successes X in n trials of a binomial experiment is called a binomial random variable.The probability distribution of the random variable X is called a binomial distribution, and is given by the formula:P(X) = Cnxpxqn−xwheren = the number of trialsx = 0, 1, 2, ... np = the probability of success in a single trialq = the probability of failure in a single trial(i.e. q = 1 − p)Cnx is a combinationP(X) gives the probability of successes in n binomial trials.Mean and Variance of Binomial DistributionIf p is the probability of success and q is the probability of failure in a binomial trial, then the expected number of successes in n trials (i.e. the mean value of the binomial distribution) isE(X) = μ = npThe variance of the binomial distribution isV(X) = σ2 = npqNote: In a binomial distribution, only 2 parameters, namely n and p, are needed to determine the probability.EXAMPLE 1Image sourceA die is tossed 3 times.

The number of degrees in the angle needed to complete a right angle 45 is its own complementary angle. == ==
If you needed to pour liquid from a 1 liter container to a 10 mL container which of the following would be most helpful?
funnel
How many random variables are needed to plot a probability distribution?
A probability density function can be plotted for a single random variable.
What is needed to develop a bionomial probability distribution?
A number of independent trials such that there are only two outcomes and the probability of "success" remains constant.
What re the three criteria needed for something to be a probability distribution?
A probability distribution must have a well defined domain - that is, the set of possible outcomes.For each possible outcome, there must be a non-negative value associated - the probability of that outcome.The sum of the probabilities, over all possible outcomes, must be 1.
What does resource allocation mean?
'Resource Allocation' is a management terminology phrase for the scheduling of activities and resources needed to complete them whilst taking into consideration both the time needed to complete and effort it will take.
What sample size is needed to disprove the hypothesis that the probability of outcome A equals 0.25?
The answer depends on what population characteristic A measures: whether it is mean, variance, standard deviation, proportion etc. It also depends on the sampling distribution of A.
When is a historgam used?
I think that you mean histogram, so I am going to go off of that meaning. A histogram is a statistical image that shows a visual impression of the distribution of data. It's purpose is to assess the probability distribution of a given variable, by depicting frequencies in a certain range of values. Histograms are used when density estimation is needed, or when one needs to estimate the probability density function of an underlying variable. More often than not, it is used in mathematics and statistics in order to determine the distribution of a specific variable at varying frequencies.
Why is a correction factor of x or - 0.5 needed?
The answer depends on the context. In probability or statistics, when using a continuous distribution as an approximation for a discrete distribution it is advisable to use 0.5 as a "continuity correction". This is to allow for the fact that the discrete variable usually cannot take values between integers. In other situations a correction may be applied to allow for measurement error.
