    random variable X

    I am a statistician and having a problem to understand that which one is correct:

    i) random variable X has ...
    or
    ii) random variable X have ....

    I tried to google both phrases and it came out 495000 and 90400 sites respecively, which means both can be used. Am I correct? If not then which is preferred by you people.

    Similarly I would like to know aboutthe followings:

    Let X denote
    or
    Let X denotes

    Which one is correct.

    Thanking you in advance.

    Re: random variable X

    Random variable X has... ("X" is singular.)

    Let X denote... (But "X denotes...")
