Answer:
15/7= 2 1/7
Step-by-step explanation:
Assuming 100% = 1, there is a 0.3 chance of 30 points, 0.55 chance of 100 points, and 0.15 chance of 400 points. Multiplying the chance with the expected values and then adding them up will give you the expected value of one roll.
0.3(30) + 0.55(100) + 0.15(400) = 124
So the expected value of a roll is 124 points
<span>If TIm received 444 points for every correct answer, and there was no penalty for wrong answers, then the number of answers he got right was 767676/444 or 1729 questions he got right. If he got 101010 answers wrong, then there were 101010+1729 or 102,739 questions on the test.</span>
