My boss says it is 85% likely I will be able to attend. So, there is an 84% chance I can carry genuine Kenyan coffee, direct from Kenya, to fuel Keith. I would need to know what type he likes though. Please let me know. Beans or ground? Type of roast?

Why the 1% difference between me and my boss? I might mess up, make the convention and discover I packed extra underwear instead of coffee.
