One of the items on a student survey for an introductory statistics course was "Rate your intelligence on a scale of 1 to 10." The distribution of this variable for the 100 women in the class is presented below. Rating 5 6 7 8 9 10 Count 15 25 39 18 2 1 What is the probability of randomly selecting a woman from the class who has an intelligence rating that is LESS than seven? none of the above (15 + 25 + 39)/100 = 0.79 (18 + 2 + 1)/100 = 0.21 39/100 = 0.39 (15 + 25)/100 = 0.4
