Normally, we use can when we make present decisions

about future ability.

 The Modals in English Grammar

MAY and MIGHT

MAY is used to express possibility:

                                It might rain today.

May, Might:  to be allowed to.

  1. c) It should be noted that the meaning of ‘Must not’ is to be obliged not to.

                You must not leave.

    He must not speak.

In order to express the idea of not being obliged to do

something, an expression such as not to be obliged to or

not to have to is generally used.

You do not have to leave.  =You may stay, if you wish

He is not obliged to speak. =He may be silent, if he wishes.

Note: The auxiliaries Could, Might can be used

To express differing degrees

                It is possible he may have called while we were out.

  1. d) Thus, Might expresses the highest degree of politeness.

                Might I observe what you are doing?

                Might I offer some advice?

  1. e) May, Might and Must used to express probability:

                somewhat probable:                     may, might

                highly probable:                              must

                He must be mistaken.

                You might be right.

    It may snow later this afternoon

  1. f) May, Might and Must used to express Affirmative:

Must (subjective obligation): Often use must to say that

                                                                                You must visit us.

Can use ‘Must’ to talk about Present or Future.
