Let Y represent the number of times a student visits a certain pizza parlor in a one month period. Assume that the following table is the probability distribution of Y:

 y         p(y)

 0          .1

 1          .3

 2          .4

 3          .2

a) State the two criteria that prove the table represents a probability distribution.

b) Find the mean ( m ) and the standard deviation ( s ) of this distribution.

c) Find the probability that a student will visit the pizza parlor at least twice in the next month.

d) Construct a histogram of the probability distribution and locate   m  on the histogram.

e) Find the probability that a student will visit the pizza parlor no more than 1 time in the next month.
