Afriend has placed a large number of plastic disks in a hat and invited you to select one at random. he informs you that they have numbers on them, and that one of the following is the probability model for the number on the disk you have chosen. which one is it?

The underlying probability distribution can't be determined  with certainty in this case from the given data, but if we have to take one it would be most preferably the 'Normal Distribution'.

Step-by-step explanation:

The distribution is most probably 'Normal Distribution' as we know that it is the most general and common distribution of all and from the central limit theorem if there is a large sample from any  probability distribution with finite mean and variance, the sample mean approaches a suitable normal distribution and for most of the distributions when the parameters tend to a certain value or may be that is ∞ , the resulting distribution tends to a suitable normal distribution , but the underlying probability distribution can't be determined with certainty in  this case from the given data.
