If two dice are rolled, the probability that the sum of observed values is equal to 13 is zero. The sum of two dice can only lie between 2 and 12, inclusive.

Is it significant to get a twelve when a pair of dice is rolled with probability of less than or equal to five tenth?
The probability to get a 12, with two dice, is 1/36.
Probability values are always greater than or equal to 0?
Yes.
What is the meaning of the word likelihood?
In statistics, a likelihood function (often simply likelihood) is a function of a statistical model. The likelihood of a set parameter values, given outcomes x, is equal to the probability of those observed outcome.
If a die is rolled what is the probability of getting a number less than or equal to 6?
Since all numbers on a die are 6 or below, the probability is 6/6, 1, or 100%.
What is unweighted mean?
It is the sum of the observed values divided by the number of observations. Each observed value is given equal weight or treated with the same degree of importance.

If two fair dice are rolled what is the probability that the total number of spots shown is equal to 15?
If two fair dice were rolled, there would be 36 outcomes. (1,1),(1,2),....,(6,6) The maximum sum would be 12. Therefore, the probability that the total number of spots shown is equal to 15 is zero.
Are the probability values always greater than or equal to 0 or less than or equal to 1 or all positive numbers?
Probability values are never negative and are always between 0-1 according to the definition Probability of A= Number of outcomes classified as A/Total number of possible outcomes
If a die is rolled what is the probability of getting a number less than or equal to 6?
Since all numbers on a die are 6 or below, the probability is 6/6, 1, or 100%.
A cumulative frequency distribution would provide?
The cumulative frequency or the probability of an observed value being less than or equal to a given value. By extension, it would also give the probability of a greater value being observed.
What is the chi square test used for?
The chi-squared test is used to compare the observed results with the expected results. If expected and observed values are equal then chi-squared will be equal to zero. If chi-squared is equal to zero or very small, then the expected and observed values are close. Calculating the chi-squared value allows one to determine if there is a statistical significance between the observed and expected values. The formula for chi-squared is: X^2 = sum((observed - expected)^2 / expected) Using the degrees of freedom, use a table to determine the critical value. If X^2 > critical value, then there is a statistically significant difference between the observed and expected values. If X^2 < critical value, there there is no statistically significant difference between the observed and expected values.
What is unweighted mean?
It is the sum of the observed values divided by the number of observations. Each observed value is given equal weight or treated with the same degree of importance.
How do calculate the probability of at most?
For a discrete variable, you add together the probabilities of all values of the random variable less than or equal to the specified number. For a continuous variable it the integral of the probability distribution function up to the specified value. Often these values may be calculated or tabulated as cumulative probability distributions.
What does fair means in probability?
From a probability perspective fair means equal probability.
