How normal distribution is better?

Normal distribution is not "better."

It is, perhaps, simpler to work with. All introductory text books and courses on statistics cover it in great detail, its properties are well-known, and there are lots of tables you can refer to.

But if the real-world situation you are trying to model does not resemble a normal distribution, then it is very bad to try to use the properties of a normal distribution or to try to force a normal distribution on your data. Doing so will give you inaccurate answers.

What are the chances of a Massachusetts mom who works part time to receive more than half the house or all of it?

Assuming this pertains to divorce proceedings, if an amicable agreement cannot be reached between the parties, the judge will decide what should be done with a residence.

What is the probability that a chosen student will be a freshman if there are 350 freshman 320 sophomores 310 juniors and 400 seniors?

The answer, rounded to one decimal place, is 25.4%. This means you have just over a one-in-four chance of choosing the freshman from the entire student population.

You can figure it out for yourself by solving this division formula:

(size of group you want to pick one from)

--------------------------------------------------------- = Probability of choosing from the group

(Total size of population you'll choose from)

For this problem, the answer is:

350 / (350+320+310+400) = 350 / 1380 = 0.253623188.... ~= 25.36%

How many combination of picking 10 numbers out of 49?

I posted a link to a site that explains this stuff really well.

If this is like Lotto numbers - you have 49 unique balls (no repetition), and you're picking 10 of them, and order does not matter - then here is the formula:

C(n,r) = n! / (r! * (n-r)!), where n is the number of things that you are choosing from, and r is the number of items that you are choosing. In this case n=49 and r=10.

49! / (10! * (49-10)!) = 8,217,822,536 {8.2178 Billion}

If this is not the type of problem you are trying to solve (like order matters, etc), then check out the Mathisfun link that I posted.
