You can have reasonable expectation based on previous experience/precedent, and on recognition of causal sequence. We rely on anticipating the future every day - we park our car and assume it won't transmogrify into an elephant while we're gone. We use a combination of past experience and logical inference to predict that the sun will rise, that we will die etc.

This mightn't be knowledge strictly speaking, but it's predictive value is so high it functions pretty much as well as knowledge would. All these predictions exist on a continuum, the further down you go the less useful the prediction - 'I'm going to live until the end of this week' ranking higher than 'my cat will learn to play the violin'.

You're talking of induction. The sun rose yesterday and the day before that so I believe it will rise tomorrow. Many would argue that induction is not knowledge at all. There is no reasoning behind induction. Of course, simplicity is inductions best ally.
