Best practice
Vary your language. While "was probably" is acceptable, alternatives like "most likely was" or "it may have been" can add nuance and prevent repetitive writing.
Common error
Avoid using "was probably" excessively without providing any context or reasoning. It can make your writing sound weak and speculative. Always offer some form of explanation or observation to support your claim.
