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 is the probability that someone will answer at least one of the eight questions correctly?
The answer to this question depends on how easy or difficult the eight questions are. If, for example, the questions were based on Godel's incompleteness theorem it is very likely that nobody could answer them - ever.

How many outcomes are possible when rolling 5 number cubes at one time?
There are 65 = 7776 possible outcomes. However, if the number cubes are indistinguishable, then these represent 378 distinct outcomes.
around 45

How many different ways can you arrange the letters in the world car?
Do you mean the word "car" (as opposed to the world car)? If so then the answer is 6, which is three times two times one.
There are three choices for the first letter. Having chosen the first, you have two choices for the second. Having chosing the first and second, you have one choice for the third.

What is the probability of rolling a sum of ten with a single toss of two fair six-sided dice?
3/36 = 1/12 = 0.0833... or 8.33... %
When rolling a cube 60 times how many times will it land on a number greater than 3?
Assuming the die is fair, the probability of a number greater than three is a half so the EXPECTATION would be that it will land on a number greater than 3 thirty times. But, this is the expectation; the actual number could be anything from 0 to 60.
How many different ways can you arrange the letters of the word addend?

6 * 5 * 4 * 3 *2

What is the probability for drawing a red or black card?
The probability of drawing a red or black card from a standard deck of playing cards is 1 (a certainty). This is because these are the only options available.
What are the Odds of rolling doubles?
Answer 1:
The odds are very easy to calculate. Simply divide the number of "valid" rolls against all possible rolls. For ease, you can write down all possible combination for the 2 dice.
1-1; 1-2; 1-3; 1-4....and so on, remember 1-4 and 4-1 are different rolls
There are 36 unique possible combination, and 6 of them are doubles, so that's 6/36 chances (and since 6 goes into 36, 6 times, this reduces to 1/6) or about 17%
Answer 2:
Another way to look at this problem, generically, is to assume we have an 'n' face dice. In most cases, dice have 6 faces (1, 2, 3, 4, 5, 6). But why not create a solution that works for any number of sides? Well, if we are trying to calculate the probability of rolling two dice (dice-1 and dice-2) of 'n' sides at the same time and having them turn up as doubles, only one of the dice really matters. Here's why. Dice-1 is guaranteed to land on a number 1-n. This will happen every time (on a fair dice, disregarding freak incidents). What we are trying to calculate is the probability that dice-2 will land on the SAME number as dice-1. Dice-2 can only land on one of 'n' values: 1, 2, 3, 4, 5, 6, ... , 'n'. For you non math folks, this just means it must land on a number from 1 to 'n' where 'n' is the number of sides on your dice. Out of all of the sides that dice-2 can PHYSICALLY land on, one of the sides MUST necessarily have the same as the value that dice-1 landed on. That is to say, if dice-1 landed on the value 3, there must be some chance that dice-2 will also land on the value 3. The probability of this occurring on a fair die is 1 divided by the total number of possible outcomes, which would be 'n'. So, really, there is a 1/n chance that dice-2 will land on the same number as dice-1. Thus, our probability for rolling doubles is simple 1/n. For our 6 sided dice example, our dice-1 lands on some value between 1 and 6 and there is a 1/6 chance dice-2 will match it.

There are 20 candies of each of the five colors.
The probability that when you select 2 candies at random exactly one of the
candies will be orange is:
P(exactly one turns out orange out of 2) = 2∙(20/100)∙(80/99) = 0.323232...
P ≈ 32%
