A manufacturer tests capacitors whose nominal capacitance is 1000 microF. The permissible tolerance is +/-10%. This means that the capacitors with capacitance of 1100 microF or greater are rejected. Rejection also applies to those with capacitance of 900 microF or less. Past data shows that the average capacitance of tested capacitors is 1000 microF With the standard deviation of 50 microF. Determine the probability that a capacitor picked at random will be rejected
