A noise voltage observed at the output of a receiving antenna can be considered as a Gaussian random variable with mean 0 and variance 10*^(-8)

(a) Calculate the probability that the magnitude of this voltage is between 4 *10^(-4) and 6 *10^(-4) ?

(b) This voltage is measured using a defective voltmeter, which always indicates a lower reading than the actual value. Suppose the voltmeter reading is 2.5*10^(-4). Calculate the probability that the error is not more than 0.5 *10^(-4).
