Hey,I don’t think this is the whole question
Answer:
There are 10 two point questions and 16 five point questions.
Step-by-step explanation:
- x = the number of 2 points questions
- y = the number of 5 points questions
- x + y = 26
- 2x + 5y = 100
- x = 10 two points questions
- y = 16 five points questions

Answer: A) 3/10</h3>
This is the probability of winning 0 dollars, aka not winning any cash prizes. So all we do is write down the probability value found in the first column.
side note: you could add all the other probabilities to get 1/5+1/10+2/5 = 2/10+1/10+4/10 = 7/10, then subtract that from 1 to get 1-7/10 = 10/10-7/10 = 3/10. Though this is a bit more work than needed in this problem.
The first one because .33 is not repeating .33 33 33 33 33 and .3 is .3 3 3 3 3 3
So that's why it's the first one.
Hope this helps!
