Question

97,98,98,99,100,100,101,102,102,103 Let’s introduce a new group of temperatures, Group D: 98.5 – 101.5. 17. True or False: Group A and Group D are mutually exclusive. 18. True or False: Group C and Group D are mutually exclusive. 19. What does B ∩ D mean? a. B and D occur simultaneously = {100.0 ≤ temperature ≤ 101.5} b. B and D occur simultaneously = {98.5 ≤ temperature ≤ 101.9} c. (B or D or both occur) = {100.0 ≤ temperature ≤ 101.5} d. (B or D occur or both occur) = {98.5 ≤ temperature ≤ 101.9} Suppose the probability of a child with chicken pox having a temperature in Group B is 25% and the probability of a child with chicken pox having temperature in Group C is 42.5%. 20. What is the probability of a child having a temperature in Group B or Group C? a. 0.675 b. 0.1063 c. 0.25 d. 0.425 21. What is the probability of a child having a temperature not in Group C? a. 0.425 b. 0.575 c. 0.25 d. 0.75
