A student was surveying whether or not his classmates liked boba or not. Of the 17 sophomores in the class, 13 liked boba and 4 did not. Of the 16 freshmen in the class, 7 liked boba and 9 did not. Write answers as simplified fractions in the format of "a/b". What is the probability that a randomly chosen student likes boba and is a sophomore? What is the probability that a randomly chosen student who likes boba is a sophomore?

ASK YOUR TEACHER It's true — sand dunes in Colorado rival sand dunes of the Great Sahara Desert! The highest dunes at Great Sand Dunes National Monument can exceed the highest dunes in the Great Sahara, extending over 700 feet in height. However, like all sand dunes, they tend to move around in the wind. This can cause a bit of trouble for temporary structures located near the "escaping" dunes. Roads, parking lots, campgrounds, small buildings, trees, and other vegetation are destroyed when a sand dune moves in and takes over. Such dunes are called "escape dunes" in the sense that they move out of the main body of sand dunes and, by the force of nature (prevailing winds), take over whatever space they choose to occupy. In most cases, dune movement does not occur quickly. An escape dune can take years to relocate itself. Just how fast does an escape dune move? Let x be a random variable representing movement (in feet per year) of such sand dunes (measured from the crest of the…
