Dinner at Home. Choose a parent with children under age 18 in the United Statesat random and ask, "How many nights a week out of seven does your family eatdinner together at home?" Call the response X for short. Based on a large samplesurvey, here is a probability model for the answer you will get:0Nights1346.7Probability 0.050.000.070.080.100.170.150.38(a) Verify that this is a valid finite probability model.(b) Describe the event X<4 in words. What is P(X<4)?(c) Express the event "eat dinner together at home at least once a week" in termsof X. What is the probability of this event?
