Neither of the two groups of students is right.
Step-by-step explanation:
If the probability that Jessica will win the raffle this year was 
, the probability that she will win the raffle in subsequent years is given that the number of students do not change. Since this is a random win, she as likely to win next year as she was this year.
Another way to explain this is to say that the probability of Jessica winning the raffle this year is independent of the probability that she wins the raffle next year. Suppose event A, is the event that Jessica wins the raffle this year, let event B be the event that she wins the raffle next year, event A and B are independent because the occurrence of event A does not affect the occurrence of event B in any way

Step-by-step explanation:
Hello! To solve this question, we can write and solve a proportion. Set it up like this: 5,880/x = 42/100. You do this, because you’re looking for the total amount of area there is. Cross multiply the values and you get 588,000 = 42x. Now, divide each side by 42 to isolate the “x”. 588,000/42 is 14,000. x = 14,000. Arizona’s total area is 14,000 square miles.
So since they gave you what y equals you plug it in into the 2nd equation. So 8x-7(x+3)=12 and you solve for x and then once you get x you plug x into either equation to get y!
