What is the probability of being dealt a sum of 19 in ther first two cards?

Assuming blackjack values, there are seven cards per suit that can be dealt first that could lead to a total of 19. Each of these has one card per suit to be dealt next to make 19, except an 8 has two. If it's a standard 4-deck situation, the odds are:

(6/13)(16/207) + (1/13)(32/207) = 128/2691

What are the probabilities of being king?

Very close to 0. There are about 7 billion people in the world and around 44 monarchies - not all of them headed by a king. But if they were, the probability would be approx 44/7 billion or 0.000000006.

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.

What is 34 percent of 125?

10% of 125= 12.5. 12.5 x 3 = 37.5

Is there a statistic for good versus evil?

This is a multi-layered question.

This is probably not the place to entertain it to any depth. Let me point to just two considerations.

First, there is a large difference between the dichotomy of 'good vs evil' and the alternative 'good vs bad'. As a tool of objective science statistics tends to avoid putting questions in moral terms.

Statistics are associated with decision theory. Although various theories attempt to provide for the consequences associated with various decisions (good and bad in approximate terms) for some reason, this type of thinking is very rarely applied.

Unfortunately.

Why are graphs used instead of frequency tables sometimes?

Visual presentation is more effective for many (though not all) people.

How do you set up a box and whiskers plot with multiple numbers?

By transferring the numerical data from the cumulative frequency curve into a box and whiskers plot.

What numbers will most likely be picked randomly using combination of 5 numbers from 1to56?

If they are randomly picked, each 5-number combination is equally likely.

If the long-term results of any lottery show that any number or combination

is more likely than others, then the game is not honest.
