In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

What does it mean for two events to be dependent?

An even is dependent of the other when one has to occur before the other can do so. Else, one can also occur with the other.

E.g. Christmas (or the winter holidays if you will) has to happen/so that/you go buy Christmas presents.

Hunger usually "depends" on the lack of food in the stomach.

---

In math, events are dependent when one event affects the probability of the other.

E.g. There is 1 red, 1 green and 1 blue balls in a container. You pick a ball out of 3. There is a probability of 1/3 = 33% of being a certain colour. Now there are only two balls in the container. The next one you pick has a probability of 1/2=50% of being a certain colour,

When you roll a dice what is the probability it will land on 1?

What is a square number less than 16 between 1-40 with a probability as a fraction?

9 is a square number less than 16. The number 9, in itself, has no probability since there is no "experiment" defined.

What does it mean low correlation to other assets?

In statistics, correlation measures how strong the relationship is between two entities. A correlation of 1.0 means that the two move in perfect tandem with each other. A correlation of zero means that the relationship between them is totally random. A negative correlation, unusual in the investing world, means that they move in opposite directions. In investing, low correlation means that different asset types have not performed in the same way: When returns on some asset types were declining, returns on others were declining less, or indeed gaining. For investors, this diversification has obvious benefits: If poor performance in one investment can be offset by better (or even good) performance in another, extreme losses in an overall portfolio will be rarer than otherwise, and the capital will grow more in the long run.

When rolling a fair dice numbered one to six what is the probability of rolling a one?

If you spun a coin 5 times how likely would it be to land on heads every time?

The probability of a spinning coin landing on heads is 50% each time.

The probability of five consecutive heads is (0.5 x 0.5 x 0.5 x 0.5 x 0.5) = 1/32 = 0.03125 = (3 and 1/8)%

What is the importance of the concept of probability?

An accurate knowledge of the probability of some event to occur allows the concepts of planning, preparing and expecting to take on meaning. If you had absolutely no idea what was going to happen from one moment to the next, it would be completely illogical for you to do any of those above things. Not to mention that the entire idea of "surprise" would be moot since everything would be a surprise.

Can -0.5 be a probability?

No. Probabilities are 'counted' as between 1 (certain) and 0 (impossible)

What is the probability of getting 2 heads if a coin is tossed thrice?

(1/2)^3 = 1/8th

Since the initial probability (assuming independence) of getting a head in a single toss is one half (1/2) we just cube this probability because of the number of events we are performing. So if you were to try to calculate the probability of a coin being tossed 6 times it would be one half to the 6th power which is 1/64.

A pair of dice is rolled What is the probability that the sum is equal to 5?

Number of possible total pairs = 36

Number of pairs which give five as a sum = {1,4},{2,3},{3,2},{4,1}

So, P(Sum=5) = 4/36 = 1/9
