If a variable has possible values -2 6 and 17 then this variable is an Integer.
The value of the distribution for any value of the random variable must be in the range [0, 1]. The sum (or integral) of the probability distribution function over all possible values of the random variable must be 1.
0.636 approx.
No, this is a discrete variable since it can assume only whole number values: 0, 1, 2, 3, ... . A continuous variable would be one such as volume of water in a swimming pool which could be measured in real number units of volume.
It would mean that the result was 2 standard deviations above the mean. Depending on the distribution of the variable, it may be possible to attach a probability to this, or more extreme, observations.It would mean that the result was 2 standard deviations above the mean.

Approximately 2 standard deviations (1.96, actually) from the mean. That is important to know that if one has a sample of 1000 values, if one selects a threshold at +/- 2 standard deviations from the mean, then one expects to see about 25 values exceeding those thresholds (on each side of the mean)
A binary variable.
The value of the distribution for any value of the random variable must be in the range [0, 1]. The sum (or integral) of the probability distribution function over all possible values of the random variable must be 1.

Given a value for the variable x, you find (calculate) the corresponding value of y. These (x, y) pairs are part of the table. You cannot complete the table because there are infinitely many possible values of x.
2,1,0,-1,-2 are the possible values of ml for an electron in d orbital.
"If y=2x, then x is the independent variable and y is the dependent variable." Also, " If x=y/2 then y is the independent variable and x is the dependent variable". Also, "The dependent variable is the one variable which is found by giving values to all the independent variables"

No.A discrete variable is a variable that can not assume all possible values within a given range.For example, if I were to conduct a survey on the number of children people had, then my answers would be numbers such as 0, 1, 2 and so forth (i.e. they would be whole numbers). This particular variable could not have a value in between these (a non integer value), such as 1.345, as this makes no sense in this context. This makes the variable discrete.
The values are : All even numbers and zero.
The number of popcorn servings sold per day is actually an exemple of a discrete variable. A discrete variable can only take on certain values within its variable range (1, 2, 3, etc). As such, the number of servings can only take on those values, that are whole numbers, without decimals. You cannot say that you have 1.5 desks in your room, for example. You have 1, 2 or 3 desks. On the contrary, a continuous variable is one that, within its variable range, can take any value. Time would be a good example. Between 2 o'clock and 3 o'clock, there are other values. A student can say it took 2 hours and 10 minutes to complete his exam, for example.
