    a) Discrete random variable

    b) Not a random variable

    c) Discrete random variable

    d) Continuous random variable

    e) Discrete random variable

    f) Continuous random variable

    Step-by-step explanation:

    a) This is discrete because we can quantify it and it can not take a decimal number and has true zero. That is, zero means absence.

    b) This is not a random variable because hair color is quality, thus it cannot be quantify.

    c) This is discrete because we can quantify it and it can not take a decimal number and has true zero. That is, zero means absence.

    d) This is continuous random variable because we can quantify it, it can take decimal number and has no true zero. For instance, 0 degree Celsius does not implies absence of temperature. Or that we say someone is a dwarf does not implies he/she has no height even though the measure scale may read zero.

    e) This is discrete because we can quantify it and it can not take a decimal number and has true zero. That is, zero means absence.

    f) This is continuous random variable because we can quantify it, it can take decimal number and has no true zero. For instance, 00:00 GMT does not implies absence of time.
