Project of mathematics in daily life?
When you buy a car, follow a recipe, or decorate your home, you're using math principles. People have been using these same principles for thousands of years, across countries and continents. Whether you're sailing a boat off the coast of Japan or building a house in Peru, you're using math to get things done.
How can math be so universal? First, human beings didn't invent math concepts; we discovered them. Also, the language of math is numbers, not English or German or Russian. If we are well versed in this language of numbers, it can help us make important decisions and perform everyday tasks. Math can help us to shop wisely, buy the right insurance, remodel a home within a budget, understand population growth, or even bet on the horse with the best chance of winning the race.

What does correlation does not mean causation mean?
People with bigger feet have higher intelligence, and people with smaller feet have lower intelligence. In other words, foot size is correlated with intelligence.
However, it's clear that if I could have made my feet bigger it would not have made me more intelligent. In other words, in increase in foot size is not a cause of greater intelligence.
That's what 'correlation does not imply causation' means.

I have included a link on outliers. The definition as given in Wikipedia is similar to those in other textbooks: In statistics, an outlier is an observation that is numerically distant from the rest of the data. It is not a rigorous definition, because "numerically distant" adds an element of subjective judgement. Values which are far removed from the typical range (or grouping) of a sample are not necessarily erroneous data. For this reason, the use of adjectives that add some doubt as "apparent" or "possible" to the term outlier is correct. See related link for examples of outliers.

A pair of dice is rolled What is the problability fo getting a sum of 2?
Assuming you meant a standard pair of dice, only 1 and 1 add to 2, since there are no negatives, and numbers only stretch up to 6, and due to that, there is no 0. Therefore, 1/36 is the probability (probability of rolling a 1, 1/6, probability of rolling a 1, 1/6, 1/6(1/6) = 1/36).
What is 6000 over 36000 as a percentage?
