2. Consider again the example of the number of languages spoken by Filipino school children. Define X to be the number of languages in which a randomly chosen Filipino child attending school can hold an everyday conversation. Assume that the probability function of X, P (x), is as shown in the following table. 2 3. 4 6. P(x) 0.663 0.226 0.066 0.022 0.019 0.004 a. What is the mean of X? b. Find the variance of X c. Find the standard deviation of X. 2. Consider again the example of the number of languages spoken by Filipino school children.
