Answer: 34 questions
Step-by-step explanation:
If you have 40 questions, you have to find out what each question is worth which was 2.5 points per question. Then you divide 85 percent by 2.5 points and you get your answer that you got a total of <u>34 questions</u> corrects to get an 85%.
We can find the number of extra clubs in the deck from the given probability, since the probability of drawing a diamond and a club is

but this would imply that

, which suggests we're taking 4 clubs out of the original deck and contradicts the problem statement that there are "too many clubs".
Perhaps the question is providing the probability of drawing a diamond, THEN a club, or vice versa. In that case, we have

and solving gives

, which makes more sense. Then the number of extra spades in the deck must be 2.
