Assume you're playing a video game and in that video game you load into different lobbies and with each lobby there's a potential chance for a boss to spawn with a maximum of 2 bosses to spawn in the same lobby at once. Each boss has an individual 26% chance of spawning into the lobby so given that both bosses have a 26% chance what are the odds of just one boss spawning when you load into the lobby. Please give me the formula aswell as an answer
