IMO E

What we need to know --> (Red haired women)/Total x 100

1) 0.05 w = red hair women ...but doesn't tell us anything about the total

insufficient

2) only tells us about red haired men

c) combining doesn't help because we don't know the total numbers of women, men or the total population

Combine 1 and 2

......................Men (I)......................Women (II)...........Total (III)
Red heir ........ 1 .................................. 1 .......................
Not red heir ... 9 .................................. 4 .......................
.......................10................................. 5 .......................

There is no relation between Men and Women. So we cannot find total value of the group.

Answer: E
