Answer 3

Lets look at each choice:
A) 32 is a number of students, it is not a relative frequency.
B) If we look at the total number of students (128) 50% prefer playing sport and 50% prefer dancing.
C) Looking at female students, 52 out of 84 prefer dancing. 52/84 converted to a percentage is not 81%.
D) When we look at the total number of students who prefer dancing (64), 52 are female. 52/64 converts to 81%.
