Suppose person a picks a number uniformly in the interval (0, n). let x be the number person a picks. suppose that independently of person a, person b picks an integer y according to the binomial (n, p) distribution, for example

c

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
