Consider the following weight readings in pounds below:
A = {weight between 100 170}
B = {weight 171}
C = [weight < 150)

13. True or False: The events A and B mutually exclusive.

14. True or False: The events A and C mutually exclusive.

15. SupposePr(A) = 0.35, Pr(B) 0.55. What is the Pr(weight > 100)?

16. What does A u C mean?
A. A and C occur = {100 <= weight <= 150}
B. A or C or both simultaneously = { weight <=170}
C. A or C occur = {weight <= 170}
D. A or C or both occur simultaneously = {100 <= weight <= 150}

17. What does A n C mean?
A. A and C occur = {100 <= weight <- 150}
B. A or C or both simultaneously = { weight <= 170}
C. A or C occur = {weight <= 170}
D. A or C or both occur simultaneously = {100 <- weight <- 150}

18. What does B U C mean?
A. B and C occur = {weight <= 150 or weight >= 171}
B. B or C or both occur simultaneously= PI this cannot happen as they are mutually exclusive events
C. B or C or both occur simultaneously = {weight <= 150 or weight >=
D. B and C occur = this cannot happen as they are mutually exclusive events

19. What does B n C mean?
A. B and C occur = {weight <= 150 or weight >= 171}
B. B or C or both occur simultaneously = {(1)} this cannot happen as they are mutually exclusive events
C. B or C or both occur simultaneously = {weight <= 150 or weight >=170}
D. B and C occur = {0} this cannot happen as they are mutually exclusive events

20. What is the probability of Bc given the information in question 3?

The radioactive spiders are loose on campus and this time they're not alone. Below is a table of the different radioactive animals along with three different mutant abilities victims have now claimed to gain. The table has the frequency of people reporting each symptom along with a total number of people bitten by that animal. Note that not everyone bitten ended up gaining a mutant ability.

Mutant Ability	Radioactive Animal
Mutant Ability	Spider	Possum	Flea	Rat	Total
No Ability	3	7	2	5
Mind Reading	9	1	6	4
Agility	10	5	3	1
Regeneration	2	4	7	11
Total					80

21. What is the probability of no mutant ability rounding to 3 decimal places?

22. What is the probability of being bitten by a flea rounding to 3 decimal places?

23. What is the probability of gaining the agility mutation AND bitten by a spider rounding to 3 decimal places?

24. What is the probability of having the mind reading mutation AND bitten by a spider rounding to 3 decimal places?

25. What is the probability of mind reading given a person was bitten by a possum rounding to 3 decimal places? (i.e. What is Pr(mind reading bitten by possum)?)

26. What is the probability of agility given the person was bitten by a rat rounding to 3 decimal places? (i.e. What is Pr(agilitylbitten by rat)?)

27. True or False: The probability of the mind reading mutation and probability of being bitten by a possum are independent events.

28. True or False: The probability of no mutant ability is dependent on being bitten by a flea.
