16. If you toss a fair coin a large number of times, assuming the tosses arc which
ofthe following is true? Once the number of flips is large enough,the number of headS will always be exactly halfofthe total number oftos""s. The proportion of heads will be about 1/2 and this proportion ",ill tend to get closer to 1/2 as the number oftosscs increases.
