There are 9 people that have a conversation with each other exactly one time.
Sedbober [7]

The question is an illustration of arithmetic sequence.

<em>The number of conversation for 19 people is 171</em>

<u />

<u>(a) 9 people</u>

Total = \frac{9 \times 8}{2}

9 represents the number of people

8 represents the number of conversation each person had

2 represents the number of people having a conversation at once (i.e 2 people at once)

<u>(b) 19 people</u>

We have:

n = 19

The number of conversation is:

Total = \frac{n \times (n -1)}{2}

So, we have:

Total = \frac{19 \times (19 -1)}{2}

Total = \frac{19 \times 18}{2}

Total = 19 \times 9

Total = 171

Hence, the number of conversation for 19 people is 171
