Explanation

In digital signatures, the public key is known to everyone.

Explanation

The given equation is a permutation of the numbers, where [E] = {4, 1, 2} represents the set of values.

The correct permutation is E = (2, 1, 4), which means:

• E1 = 2
• E2 = 1
• E3 = 4

Explanation

Explanation

To calculate the number of ways seven people can sit around a table, you can use the formula for permutations of n objects taken r at a time in a circular arrangement:

P(n,r) = (n−1)!

Where n is the number of objects (people) and r is the number of positions to fill (seats).

So, for seven people sitting around a table, there would be 

(7−1)! = 6! ways.

6! = 6 × 5 × 4 × 3 × 2 × 1 = 720

Explanation

The formula for the number of possible communication channels in a round table meeting is: n(n-1)/2.
