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.

Given:

men= 25

women = 20

Thus, there are 25 possibilities for vice-president.

So,   20+25–2=43 possibilities for secretary.

as, no person can hold multiple positions, and the secretary can be either male or female.

20x25x43=21500.

Now,

The total number of ways,

=20x25x43 +20x25x43

= 4,043,000.
