A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is a probability of an event?

Lets first start by defining some terms:Probability (P) in statistics is defined as the chance of an event occurring.Probability experiment is a chance process that leads to results called outcomes.An outcome is the result of a single trial of a probability experiment.A sample set is the set of all possible outcomes of a probability experiment.An event consists of a set of outcomes of a probability experiment. An event can be one outcome or more than one outcome. The event can be anything from flipping a coin, to rolling a die, to picking a card.The probability of any event (E) is:(# of outcomes in E) / (total # of outcomes in sample space)For example: Find the probability a die is rolled and you get a 4?We know that there are 6 possibilities when rolling a die. We can either rolled a 1, or a 2, or a 3, or a 4, or a 5, or a 6.Using the equation above:P(rolling a 4)= 1/6The event in this case is rolling a 4.

Why cant a probability be greater than 1?

Probability is the chance something is going to happen. It has to be DO/PO DO= desired outcome PO= probable outcome. The probability can not be 1 because it has to be a percent chance of out of a fraction, which are both smaller than 1.

What is the probability of getting a number greater than 3 or an odd number if a die is rolled one time?

If the die is numbered 1,2,3,4,5,6, then the numbers you could roll on that time include: Odd Numbers: 1,3,5 Greater than 3: 4,5,6 Apparently, every number appears but 2, so there is a 1/6 chance of NOT getting the favorable outcome. The favorable outcome is the chance of prevailing in the event's request, and in this case, has a 5/6 chance of taking place. So.. the probability is 5/6 of a chance, 83.333%, or .83 of a chance, repeating 3.

Which is better a 0.05 level of significance or 0.01 level of significance?

0.05 level of significance indicates that there is a 5% chance (0.05) that, under the null hypothesis, the observation could have occurred by chance. The 0.01 level indicates that there is a much smaller likelihood of the event occurring purely by chance - much stronger evidence for rejecting the null hypothesis in favour of the alternative hypothesis.

What is the probability that if three dice are rolled simultaneously then two dice will come up with same number?

This depends on if you want at least two of the dice to be the same number, or exactly two of the dice to be the same number.For the first scenario: Roll the first die, and get a number. Roll the second die, and there is 1/6 chance that it'll be the same as the first one. Now if it's not the same (5/6 chance) then the third die has 1/6 chance of being the same as the first, and 1/6 chance of being the same as the second. So we have:1/6 + 5/6*(1/6 + 1/6) = [simplified] 4/9 or about 44.44%chance that at least two are the same.For the second scenario: With three dice, there are 216 possible outcomes (6 x 6 x 6). So we know that there is a 4/9 chance that 2 or more will be the same: (4/9)*216 = 96 outcomes. Now 6 of these outcomes will have all three dice the same, so subtract 6 from 96 = 90. There is a 90/216 = 5/12 or 41.67% chance that exactly two dice are the same.

Why is probability important to a scientist?

Some but not all scientific models are based on the ability to determine the likelihood that a given experimental outcome has happened by chance alone. If you have an accurate understanding of how the variables in the experiment change when nothing in particular is affecting them, then you have a way to establish some confidence that your outcome is the result of your experimental procedure and not the result of purely random events. The experimental 'lingo' is that the researcher has to determine if the 'Null Hypothesis' can be rejected. The Null Hypothesis is that the experimental outcome is not significantly different from what you would expect if the experiment had no effect at all.As an example, if the probability in the natural world is that some event will happen by chance only one tenth of one percent of the time, then when I observe that event as my experimental outcome, I can be reasonably sure that my procedure has brought about the event; it is so unlikely that it happened by chance. It is not perfect, but few scientific procedures are. This also highlights the importance of replicating studies or of doing meta-analyses of experimental data gathered in many experiments to further reduce the likelihood that observed outcomes are nothing more than chance events.
