We investigate deviation from the tribimaximal mixing in the case of ultrahigh energy neutrino using the ICECUBE detector. We consider the ratio of the number of muon tracks to the shower generated due to eletrons and hadrons. Our analysis shows that for tribimaximal mixing the ratio comes out around 4.05. Keeping \ensuremathθ12 and \ensuremathθ23 fixed at tribimaximal value, we have varied the angle \ensuremathθ13=3\ifmmode^∘\else\textdegree\fi, 6\ifmmode^∘\else\textdegree\fi, 9\ifmmode^∘\else\textdegree\fi and the value of the ratio gradually decreases. The variation of ratio lies within 8% to 18% from the tribimaximal mixing value and it is very difficult to detect such a small variation by the ICECUBE detector.
