May and might can also both be used in the context of permission, often as what’s thought to be a more polite substitute for can, as in May/Might I use your restroom? In responses to such questions, it’s usually may that’s used, as in Yes, you may. Some people might intend to use the two words this way, but in practical terms they are often interchangeable when used in this sense-they usually mean just about the same thing. Traditionally, might is considered a weaker form of may-meaning that it expresses a lower degree of possibility that something will happen.

Might and may can both be used as auxiliary verbs ( helping verbs) that express possibility, as in We may/might have some left-let me check.
