interprets the mean and the variance of a discrete random solves problems involving mean and variance of probability distributions. A. Classify the following random variables as discrete or continuous 1. X = the number of mobile phones sold in one week in AB store 2. Y = the weight in pounds of newly born babies in a hospital nursery 3. X = the number of cars in a parking lot every noon 4. Y = the number of gifts received by a birthday celebrator 5. X = the length of time spent in playing video games in minutes B. Determine whether the distribution represents a probability distribution. Explain your an LD N O X x P(x) 1/6 1/6 1/3 1/6 1/6 P(x) 0.35 PERFORMANCE TASK #1 Construct a probability distribution for the data and draw a histogram of the distribution 8. The probabilities that a surgeon operates on 3, 4, 5, 6, or 7 patients in any one day 3 4, 5, or 6 are 12, 1/6, 1/12, 1/12, 1
