Dears/madam, I want help on the following question:

1.Three firms are considering entering a new market. The payoff for each firm that enters is 150 / (150 divided to n), where "n "is the number of firms that enter. The cost of entering is 62.

a. Find all the pure-strategy Nash equilibria.

b. Find the symmetric mixed-strategy equilibrium in which all three players enter with the same probability.
