The number of possible groups or combination of three men can be formed from 10 is 120.
According to the given question.
Total number of men in a company, n = 10.
Number of men to be selected, r = 3
As we know that, What is a combination in math?
Image result for what is combination
A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Therefore, the number of possible groups or combination of three men can be formed from 10
= 
= 10!/ 3!7!
= 10(9)(8)/3(2)
= 5 × 3 × 8
= 120
The number of possible groups or combination of three men can be formed from 10 is 120.

Answer:
Step-by-step explanation:
you need to mutpliy all or your numders 17 x 4 x 8 x 9 = 4896m
Answer:
Step-by-step explanation:
a). tan(75°) = 
= 
k = 
k = 2.947
k = 2.95 cm
b). cos(52°) = 
s = 
s = 25.988
s ≈ 25.99 cm
c). sin(5°) = 
= 
q = 
q = 184.727
q ≈ 184.73 cm
