Jody checked the temperature 12 times on Monday, and the last digit of the temperature was odd six times more than it was even. On Tuesday, she checked it 18 times and the last digit was odd eight times more than it was even. Determine which series is closer to the 50/50 ratio of odd/even expected of such a series of temperature checks.

Question

Jody checked the temperature 12 times on Monday, and the last digit of the temperature was odd six times more than it was even. On Tuesday, she checked it 18 times and the last digit was odd eight times more than it was even. Determine which series is closer to the 50/50 ratio of odd/even expected of such a series of temperature checks.
A. The Monday series is closer because 1/6 is closer to 1/2 than is 1/8.
	
B. The Monday series is closer because 6/12 is closer to 0.5 than is 8/18.
	
C. The Tuesday series is closer because the 13/18 is closer to 0.5 than is 9/12.
	
D. The series closest to the theoretical 50/50 cannot be determined without knowing the number of odds and evens in each series.
