Calculate the following probabilities for the spinner (assuming the spinner is fair).
1) What is the probability of obtaining $800 on the first spin?
P($800)=1/8
2) What is the probability of obtaining $400 on the first spin?
P($400)= 1/8
3) Is it just as likely to land on $100 as it is on $800?
4) What is the probability of obtaining at least $500 on the first spin?
5) What is the probability of obtaining less than $200 on the first spin?
6) What is the probability of obtaining at most $500 on the first spin?
7) If you spin the spinner twice, what is the probability that you will have a sum of $200?
8) If you spin the spinner twice, what is the probability that you will have a sum of at most $400?
9) If you spin the spinner twice, what is the probability that you will have a sum of at least $1500?
10) If you spin the spinner twice, what is the probability that you will have a sum of at least 300?
11) Given that you landed on $100 on the first spin, what is the probability that the sum of your two spins will be $200?
12) Given that you landed on $800 on the first spin, what is the probability that the sum of your two spins will be at least $1000?

Fine, you get a 17.
