Probability

The first thing to do is to work out how many ways there are without those 2 people minding. There are 5 possibilities for first place, 4 for second and so on, so the number of ways is 5x4x3x2x1 = 120.

The next step is to work out how many of these possibilities have the two people sitting next to each other. There are 4 ways in which two people can sit next to each other. For each of these ways there are two possibilities, one with one person on the right, and the other with them on the left. For each of these 8 ways, there are 3x2x1=6 ways the other people could have sat. So there are 8x6=48 invalid ways in total.

120-48 = 72

So there are 72 ways 5 people can sit in a row if 2 of them insist on not sitting together.

Is it?

Let's say you flip a coin three times, and it comes up tails each time. You may state that from your experience, tails is preferred overwhelmingly.

But three tails is likely to occur approximately 12% of the time, and three heads also will occur 12% of the time.

So, instead of asking why coin flips are biased to the tails, perhaps it is better to ask what evidence exists showing that one side is more likely to occur than another. I couldn't find any. I attach the link on coin flips.

In other words you will never know unless of course you count the seconds its in the air and look what side it lands on. That always works.

In order for 4 red marbles to be one-third of a group and 3 blue marbles to make up one-fourth of the same group the number has to equal 12.

I bet that you will find it printed on the back of any Florida Lotto ticket.

suppose you flipped a coin 100 times you might have flipped heads 50 time and tails 50 times

No it is not, Les then 20% of the worlds men are circumcised and the procedure is usually inflicted upon them before they are old enough to stop it from being done to them. This us usually done in answer to a religious or cultural requirement and in some cases for so called therapeutic reasons reasons. Medial authority's see no advantage in routine circumcision and say that the penis should be left intact unless treatment is required for an existing condition that can not be treated in any other way.

You can convert this to base ten by re-writing 3096 as a summation of hex powers:

3*16^3 + 0*16^2 + 9*16^1 + 5*16^0 = 12437 in base 10

The actual number of times 4 comes up is impossible to find, but the expected value of 4 coming up if you toss a 6-sided die 30 times is 5 times.

It can be but need not be.

With only the information that is given in the question, the answer is infinitely many ways. A single square can be placed anywhere, and rotated through o=90 degrees.

accumulated binominal distribution 6*f(k;n,p) = 6*f(5;5,1/6)

This is the definition of a "barrier spit".

(A tombolo is a sandbar that connects the mainland to an island, forming a permanent or temporary isthmus, and the island can be known as a "tied island".)

1 in 6. There are six possible numbers, and it is one of those, so on one roll you have a one in six chance of rolling a six or any other individual number.

The multiples of 3 that can be rolled are 3 and 6

Therefore probability of a success is 2/6 or 1/3

3*2*1 = 6 ways.

126 combinations.

Remember that the order does not matter.

The probability of heads is 1/2.

the chances of getting a two is 1/6

1/6x100=100/6=50/3

A sum of 4 is more likely. Out of the 36 possible outcomes with a pair of 6-sided dice, only one will have a sum of 2 {1-1}. Three of the possibilities sum to 4. {1-3, 2-2, 3-1}
