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.
