c) interpret (in words) the notation p(x = 2).
d) find p(x > 2). (5 points)
3. a study of social mobility in america examined the social class attained by the sons of lower class fathers. social classes were numbered from 1 to 5 with 1 representing the lower class and 5 the higher class. consider the random variable x to the class of a randomly chosen son. the study found the following distribution:
son's class1 2 3 4 5
probability0.48 0.38 0.08 0.05 0.01
a) what percent of the sons reached the highest class?
b) check that this distribution meets the requirements of a discrete probability distribution.
c) what is p(x < 2)?
d) what is p(x = 2)?
e) write the event: a son of a lower-class father attains one of the highest two social classes in terms of x. (6 points)

First work with stencil one. use a combination of reflections, rotations, and translations to see whether stencil one will overlap with the original pattern. list the sequence of rigid transformations you used in your attempt, noting the type of transformation, the direction, the coordinates, and the displacement
