What is the probability of rolling less than five on a die?
Assuming it is a regular 6 sided die, it would be 4/6 or 2/3.
Difference between variables and probability distribution?
Assuming you mean random variable here.
A random variable is term that can take have different values. for example a random variable x that represent the out come of rolling a dice, that is x can equal 1,2,3,4,5,or 6.
Think of probability distribution as the mapping of likelihood of the out comes from an experiment. In the dice case, the probability distribution will tell you that there 1/6 the time you will get 1, 2,3....,or 6. this is called uniform distribution since all the out comes have that same probability of occurring.
The probability of 10 heads in a row is (0.5)10 = 0.000977 = 0.0977% .
It makes no difference what has come before or what comes after.
What is the probability of 6 green marbles?
We can't answer that without knowing what else is in the bowl.
What is the probablity of rolling a number greater than 2 on one roll of a die?
Let say the dice has n sides
Let first search for the probability to roll a number less or equal to 2
Probability to roll a 1 = 1/n
Probability to roll a 2 = 1/n
Probability to roll a 1 OR a 2 = Probability to roll a 1 + Probability to roll a 2
= 1/n + 1/n = 2/n
Probability to roll a number greater than 2 = 1 - (Probability to roll a 1 OR a 2)
= 1 - 2/n = (n-2)/n
If n = 6 then the result is (6-2)/6 = 4/6 = 2/3
How many possible outcomes are there of tossing a coin 30times?
That's the same as the highest binary number you can write with 30 bits.
It's 230 = 1,073,741,824 .
Get started.
I've never heard of it but i have thought about it before. i mean it can be vaporized so im sure it can be condensed. the confusing part is that it is a solid. i came up with a design and that would be to hook up a THC vaporizer to a bottle filled with everclear. put the hose from the vaporizer in the bottle, so the vaporized THC would bubble up through it. you would have to make sure the alcohol is cold enough to condense it quickly. then evaporate the alcohol and you would have somewhat pure THC (i believe its a white powder when its pure.) using this method you can eliminate the other substances that are alcohol soluble but don't vaporize.
What are the chances of getting hit by a tree?
Zero, or, actually, so close to zero that for all practical purposes you can consider it to be zero.

Assume a coin is tossed 100 times what is the probability of seeing 50 heads?
If the coin is fair and balanced, like Fox, then the probability is 50%.
They are simply convenient notations. In fact, in binary, 10 is two.
5/12
Consider the possibile outcome of two rolls of a die (where order matters):
(1,1)
(1,2)
(1,3)
.
.
.
(4,6)
(5,6)
(6,6)
There are 6*6=36 possible outcomes. Of these, the following would achieve the result desired:
(1,2)
(1,3)
(1,4)
(1,5)
(1,6)
(2,3)
(2,4)
(2,5)
(2,6)
.
.
.
(5,6)
For the first die equal to 1, there are 5 successful results. For the first die equal to 2, there are 4 successful results....For the first die equal to 5, there is 1 successful result. The total number of successful outcomes=5+4+3+2+1.
So the probability that the desired outcome is obtained=(5+4+3+2+1)/36=15/36=5/12.
The lowest number I can roll on a die is 1.
In ten rolls, that's a minimum of ten; I cannot make it 8 or less.
Zero is a foul throw.
Solutionsn of Moment-generating functions?
Your question did not identify one distribution in particular. I have provide in the related link the moment generating functions of various probability distributions.
If you roll a fair number cube1 time about how many times can you expect to roll a 3 and then a 5?
Never. If you roll it 1 time, there can be no "then".
What is the chance of pick 4 black cards out of a deck?
1/2*25/51*24/50*23/49
if cards are not replaced
What is the relevance of probability and statistics in the field of information technology?
In the field of IT you are dealing with probabilities all day long. How long will the hardware last, how can you keep the signal for the network strong all over the building, how will adding a new group of computers impact the network, or heaven forbid your network come under attack and you need to keep damage to a minimum while fending off the attack. IT professionals think in probabilities. They're always running scenarios through their heads to come up with and fix problems before they occur.
