[Haskell-cafe] Generate 50 random coordinates

My intention is to generate 50 random coordinates like (x,y).

myrand :: Int
myrand = randomRIO(1::Int, 100)

rf=[(myrand, myrand) | a <- [1..50]]

My short program is like this. However, GHCI say that the return type of
randomRIO is IO a while the function defined by me is Int. Since I only need
a integral type as my cooridinate, could you tell me how to fix this?
