Asociologist randomly selects single adults for different groups of three, and the random variable x is the number in the group who say that the most fun way to flirt is in person. determine whether a probability distribution is given. if a probability distribution is given, find its mean and standard deviation. if a probability distribution is not given, identify the requirements that are not satisfied. x p(x) 0 0.087 1 0.328 2 0.416 3 0.169 does the table show a probability distribution? select all that apply. a. yes, the table shows a probability distribution. b. no, the random variable x's number values are not associated with probabilities. c. no, the random variable x is categorical instead of numerical. d. no, the sum of all the probabilities is not equal to 1. e. no, not every probability is between 0 and 1 inclusive.

A. Yes, the table shows a probability distribution.

Step-by-step explanation:

In a probability distribution, none of the values can be negative or over 1.  Additionally, all of the values must sum to 1.

Our probabilities are:

0.087; 0.328; 0.416; and 0.169.  None of these are negative and none are over 1.

0.087+0.328+0.416+0.169 = 1.00; this means that this is a probability distribution.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

both equations and proportions are better.
