The above questions cover wide variety of ways they can be asked. Further variations can be around asking different kinds of probabilities than the ones above e.g. 2014Q16 instead of asking 2 consecutive days can ask 3 consecutive days, not 2 consecutive days, 2 out of 3 days or at least 1 day. Similarly, 2017Q15 can ask to calculate probability of greater than an amount or less than certain amount. Similar variations can be applied to every question.
