there would be 26 handshakes if they were all done at once

### If each OF seven persons in a group shakes hands with each of the other six persons then a total of forty two handshakes occurs?

The correct answer is 21. The first person shakes hands with the other 6 people. The second person shakes hands with 5 people because they already shook hands with the first person. The third person shakes hands with 4 people because they already shook hands with the first and second person. The fourth person shakes hands with 3 people because they already shook hands with the first, second, and third. The fifth person shakes hands…

### 12 members were present at a board meeting each member shook hands with all of the other members before and after the meeting how many hand shakes were there?

66. Each of the 12 members shook hands with the 11 other people. That would make 12*11 hand shakes. BUT, the A shaking B's hand is the same event as B shaking A's hand so all these handshakes are double-counted. The actual number is half that ie 33. If you are more familiar with combinatorial mathematics, the answer is the number of combinations of two obejects from 12, which is 12C2 = 12*11/(2*1)

### There are five people in a room Each person shakes the hand of every other person exactly once How many handshakes are exchanged?

Everyone shakes hands with 4 other people. Since there are 5 people in the room this would suggest there are 5*4 = 20 handshakes. However, you would then be double counting handshakes: A shaking hands with B and B shaking hands with A is, in reality, only one handshake. Thus there are 5*4/2 = 10 handshakes in all.

### How many hand shakes will occur between two teams a team consisting of 11 players?

Assuming players only shake hands with members of the other team and not their own team mates, there would be 11 players on one team, each of whom would shake the hands of 11 players on the other team. That makes 11*11 = 121 handshakes in all. If the players shook hands with everyone else, irrespective of which team they were on, there would be 22*21/2 = 231 handshakes.

### How many handshakes will there be in total if 10 people shake hands with each other?

"Each other" leaves this very open-ended; that depends on if A shakes with B or A shakes with B & C, OR if A shakes with all the other nine, etc. I would say the answer would have to be one of two: 10 or 100. If each person chooses only one to shake with, it would be ten. IF each person shakes with everyone there, all ten, it would be 100. Since this question…

### In a party everyone shakes hand with each other. If total number of handshakes is 780 how many people were there?

There were 40 people at the party. Let n be the number of people at the party. Each person shakes hands with every other person, so each person shakes hands with (n - 1) people, a possible total of n(n - 1) handshakes. But when person A shakes hands with person B, B also shakes hands with A, so each handshake would be counted twice. → number_of_handshakes = n(n - 1)/2 total number of handshakes…

### If each of the 9 US Supreme Court justices shook hands with each of the other Justices once and only once how many handshakes would take place?

If nine people each shook hands with everybody else once, a total of36 handshakes would take place. Here is the easy, simple and elegant way to solve this: 9 x 8 = 72 72 ÷ 2 = 36. This is the harder way, but it might be easier to understand: The first person shakes hands with eight other people, because there are nine people total and they can't shake hands with themselves. The next person…

### At the end of a banquet 5 people shake hands with each other How many handshakes will there be in total?

Each person shakes hands with every other person at the end of the banquet. When person 1 shakes hands with person 2 that constitutes one handshake even though 2 people are involved. So the answer is 10 total handshakes because the 1st person will have 4 total handshakes(because he can't shake hands with himself, he has 4 and not 5 total handshakes), and then the 2nd person will have 3 total handshakes (you wouldn't say…

### If there are 50 people at a party and they all shake hands once how many hand shakes will there be?

250...? yes perhaps or as few as one if they all hold hands & shake together at once or 49+48+47...+3+2+1 totaling 1225 i think would be the normally intended answer but if they deliberately try for the most possible hand shakes & so also shake hands with themselves once as well then it could be as many as 1275 in all nice question tho

### If 7 girls shake hands only once how many handshakes does that make?

The question is ambiguous: If each girl shakes one other person's hand once, then there are seven (7) handshakes. If each girl shakes each other girl's hand once, then there are 7 x 6 x 0.5 = 21 handshakes (each girl x each other girl x cancelling out the doubles). Another way to look at this one: If each girl shakes each of the other girl's hand once, there would be 42 shakes (each girl…

### What will be the sutable preposition for' he shook me..... the hand and helped me off with my coat.?

### If you have 28 hand shakes how many people in the room?

i dont know there could be other peolple in the room besides the people doing hand shakes but if there werent, and there were only two people to each hand shake, there would be 56 people in the room. Or if you mean a general hand shake that you did 28 times, there could only be 2 people in the room.

### 28 people shake hands once with everyone in the room how many hand shakes would take place?

Actually, that is incorrect. Not everyone would shake hands 27 times with another person, otherwise there would be people shaking hands more than once. I'm not entirely sure of the rule for this but this will help. 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 28 0 1 2 3 4 5 6 7 8…

### How many lines in 8 non collinear points?

28 Good question. This is an 'analogue' of this puzzle: "Eight people meet for the first time. If they each shake hands with everyone else, how many handshakes are there?" There is a formula, but who would remember it? Imagine you and I are both among the eight people. You would shake hands with seven others. I would say the same thing, and so could each of the others. That gives 8x7 = 56, but…

### Why do people shake hands when they greet each other?

Because it's a way for each person to acknowledge the other. Answer Shaking hands starts back in the early 1800s and was as good as a written contract for a promise or a deal. Men in those days NEVER shook hands with a woman (would either bow or kiss the top of her hand when she extended it.) With women in these modern times plying for a position in the man's business world it is…

### If you had cuts and scars all over your hands but wherever you go people always either look or talk about your hands is there a way how you can get rid of your old skin and replace it with new skin?

Hide them like in your pockets, but I would just not be afraid of what people say .. I would show off my hands and if they ask you "what happened?" then tell them the truth but if it's personal make something up. But don't be afraid to show who you are it doesn't matter what people say. Don't let people change who you are.
