Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

What are the most likely sums to be rolled on two regular dice?
- 1 + 6
- 2 + 5
- 3 + 4
- 4 + 3
- 5 + 2
- 6 + 1
What is the probability that a card drawn from a standard deck is a heart or an 8?
the probabiity that you draw a heart is 13/52 or 1/4, since a quarter of the cards are hearts. Since you want to know the probability of BOTH events happening, you multiply the two. One half times one fourth is 1/8, or A.

Does a large percent Relative Standard Deviation number indicate less precision?
Only if you assume that the true values are supposed to be the same every time. Otherwise, it is also possible that there is, indeed, a lot of variation among the values.
How many outcomes are there in the sample space for rolling 1 die?
It depends on how many sides your die has. If it has 6 sides, then there are 6 possible out comes.
it is 6/9 simplifyyou get 2/3.
Density function of a continuous random variable?
I am not quite sure what you are asking. If this answer is not complete, please be more specific.
There are many probability density functions (pdf) of continuous variables, including the Normal, exponential, gamma, beta, log normal and Pareto.
There are many links on the internet. I felt that the related link gives a very "common sense" approach to understanding pdf's and their relationship to probability of events.
As explained in the video, a probability can be read directly from a discrete distribution (called a probability mass function) but in the case of a continuous variable, it is the area under the curve that represents probability.
How many different arrangements of the letters in the word BETTER are there 180 360 720?

Who do you calculate in a z-score for 120 plus 0.840 times 17.6?
120 + 0.84*17.6 is 134.784
The probability associated with a z-score of 3 is 0.0013
By z = 6, it drops to 1 billionth.
A z-score of 10 or more is near enough 0 to make no difference.
Are you sure about the question? Also, whatever the question, you do not calculate someone!
