Expert writing Tips

Best practice

Use "is improbable" to express a calculated assessment of low likelihood based on available evidence, rather than a gut feeling or unsubstantiated opinion.

Common error

Avoid using "is improbable" when "is impossible" is more accurate. "Improbable" suggests a chance, however small, while "impossible" indicates no chance at all.
