Answer:
no
Step-by-step explanation:
Since there are 10 persons in the group who do not know one another, the real number of handshakes will be 45.
<h3>What is combination?</h3>
In probability theory and other branches of mathematics, the term "combination" refers to a succession of results where the order is irrelevant. A combination is a selection of all or a portion of a group of items, regardless of the sequence in which the items are chosen. Combinations and permutations may appear to be synonyms. However, they are defined differently in probability theory. Combinations: The sequence of results is irrelevant. Permutations: The sequence of events matters.
Here,
Total number of handshakes = 10C2 = (10 × 9)/2 = 45 handshakes.
When 10 people are shaking hands, each one will shake hands with 9 others.
The total number of handshakes in actual = 90/2 = 45 handshakes.
The total number of handshakes in actual will be 45 handshakes as there are 10 people in the group who do not know each other.
