  1. Interesting. The mathematical definition of expectation is not the rather nebulous everyday understanding. So how could one word a question to test the former?
    And the final “select” should be “get”.

    1. Thanks, tom. You gotta have something like “on average” in the question. Your point on “get” rather than “select” is a very good one.

  2. As marty pointed out, the word average is missing. I don’t think that Y7 students know about distributions to operate with the expected value terms.
