21 0.2 2. Find the variance and the standard deviation of the probability distribution of the random variable X which can take only the values 2, 3, 5, 7, 11, and 13, given that P(2)= 0.15, P(3)= 0.25, P(5)= 0.15, P(7)= 0.10, P(11) = 0.30, and P(13)= 0.05 3. A radio station has six telephone lines. If the host is unable to talk or is talking to another person, the other callers are placed on hold. When all lines are in use, others who are trying to call in get busy signal. The probability that 0, 1, 2, 3 or 4 people will get through is 0.22, 0.10, 0.21, 0.23, and 0.24, respectively. Find the variance and the standard deviation for the distribution. 237
