    The value of 200 would really "trow off" the mean, but not the median, so I would agree with your choice.

    46. Unless you have a magic coin that "remembers" what went before, the 14th flip has a prob of heads of 1/2

    49. since each of the remaining 4 digits could be one of 10 digits, there would be 10^4 or 10000 of them
