How often do partner events occur in Monopoly Go?

In Monopoly Go, which appears to be a variation of the classic board game Monopoly, partner events aren't a feature one would typically expect to find as part of standard gameplay. The traditional Monopoly rules do not include any components specifically labeled "partner events." Instead, the game focuses on individuals or teams buying properties, collecting rent, and attempting to bankrupt opponents. If "Monopoly Go" refers to a specific digital or thematic variation with unique mechanics such as partner events, it would be best to consult the specific rules or guidelines associated with that version since each Monopoly spin-off can have its own set of rules and features that differentiate it from the standard board game.
