Determine which deal is closer to the 50/50 ratio of red/black expected of fairly dealt hands from a fair deck and why. A. The first series is closer because 1/10 is farther from 1/2 than is 1/8. B. The series closer to the theoretical 50/50 cannot be determined unless the number of red and black cards for each deal is given. C. The second series is closer because 20/30 is closer to 1/2 than is 14/20. D. The first series is closer because the difference between red and black is smaller than the difference in the second series. 5.0 Points Question 21 of 40 Among a random sample of 150 employees of a particular company, the mean commute distance is 29.6 miles.
