I've been casually doing my logics homework for a week now but this one exercise confuses me alot. You have to translate these sentences into proposition (using ? and ? and ¬ and =>). All these seem the same to me tho: a) If there are atleast 10 students then the class will start b) De class will only start if there are atleast 10 students c)De class will start if there are atleast 10 students d) The presence of atleast 10 students is sufficient so that the class will start e) The presence of atleast 10 students is required so that the class will start Hope someone can translate these... Sorry for my bad english btw!
