I am assuming that by random you mean uniformly at random (that
is, the probability of generating i is 1/5)
map the following pairs of numbers (1, 1), (1, 2), (1, 3), (1, 4), (1,
5), (2, 1), (2, 2) to 1, 2, .. , 7 respectively
let p_i denote the pair corresponding to the number i (e.g. p_1 = (1,
random generator is
uniformly distributed

suppose given function returns the random numbers between 1 -5 then
you can have
(given + given) % 7 +1

Given a program which can generate one of {1, 2, 3, 4, 5} randomly.
How can we get another generator which can generate one of
{1,2,3,4,5,6,7} randomly?
Thank you!
If you generate random 1 to 5 twice, there are 25 equally
Why can't we simply take the 1..5 random number, multiply by 7 and
divide by 5.

Then you will get only the following numbers
(1*7)/5 = 1
(2*7)/5 = 2
(3*7)/5 = 4
(4*7)/5 = 5
(5*7)/5 = 7
What you will do to get 3 and 6?
