2. Randomly select a person aged 19 to 25 years and ask, "In the past seven days, how many times did you go to an exercise or fitness center or work out?" Call the response Y for short. Based on a large sample survey, here is the probability model for the answer you will get. Days: 2 3 4 5 Probability: 0.68 0.05 0.07 0.08 0.05 0.04 0.01 (a) Complete the table. (b) Calculate the mean and standard deviation for the distribution. (c) Describe the event Y <5 in words. What is P(Y <5)? (d) Express the event "worked out at least once" in terms of Y. What is the probability of this event?
