**Martin**, Sunday, August 28, 2011 at 2:41amvariance = 4, so standard deviation = 2 (because squareroot of 4 is 2)

160 - 166 = -6 = -3 standard deviation.

You take out a normal distribution table and you find out that a standard deviation of -3 or less happens only 0.13% of the time.

Answer : 0.13%
