AGREEMENT OF SUBJECTS ONE OR MORE, ONE IN THREE, ONE OUT OF FOUR, AND THE LIKE WITH THEIR VERBS


One or more is a compound subject, the second element of which is plural, and it always takes a plural verb: One or more of them are coming tomorrow. (See AGREEMENT OF COMPOUND SUBJECTS WITH THEIR VERBS AND SUBSEQUENT PRONOUNS.) But one out of any plural number is still one and requires a singular verb: One out often students was late.	1
