On a party six people shake hands: each one shakes hands with everybody else (only once). How manyhandshakes does that make in total?

15

Step-by-step explanation:

This is a handshake question.Its logical. If there are six people and each one shakes hands with everyone only once. Then the first person would shake the rest 5 (5 handshakes), the second person would shake only four persons because he had already shook the first (4 handshakes), third person would shake 3 persons (3 handshakes) . and this pattern will continue until the last handshake. The last person would have already had a handshake with everybody so we assume 0 for that case. So we have 5+4+3+2+1+0 = 15 handshake

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
