Analysis of wrong questions This question is easy to make mistakes in terms of unclear examination and thoughtlessness.

Positive solution: (1)50 points, 10 questions must be all right.

Of the remaining four questions, the probability of two answers is, the probability of one answer is, and the probability of the other answer is, so the probability of getting 50 points is: p =?

(2) According to the meaning of the question, the score range of this candidate is {30, 35, 40, 45, 50}.

30 points means that only 6 questions are done correctly, and everything else is done wrong, so the probability is

The probability of getting 35 points can also be drawn as follows:

The probability of getting 40 points is:

The probability of getting 45 points is:

The probability of getting 50 points is:

So you are most likely to get a score of 35 or 40.
