ollegr [7]

Answer:

Explanation:

I will give a basic hint to understanding this problem

Prevailing technique or what is best known as "Dominant Strategy" is an activity profile that is best for a specific player review of what different players are picking. for this situation there is no prevailing procedure for any player on the grounds that there is no single activity profile that expands the result for any player.

So we can say from this observations that the following is valid;

  • A doesn't have a dominant strategy

  • B doesn't have a dominant strategy

There are two Nash equilibria for this situation. Both the organizations are charging a low cost and both the organizations are charging a significant expense.

As such they can augment their benefit given what the adversary is doing.

I hope this explains the observation seen.

cheers I hope this helps
