D. rift valleys.
Trenches occur at convergent oceanic plates; fossils are extremely old bones, bodies, or footprints, which have gotten so old the intervening years have turned them into rock; U-shaped valleys are valleys which are shaped like the letter U, and are usually formed by glaciers, which tend not to occur underwater very often.
The probability that <em>a college student is involved in a club and studies 4 or more hours per day </em>is <em>9.92%.</em>
Data and Calculations:
College student population = 10,000
Students involved in a club = 35.7% or 3,570 (10,000 x 35.7%)
Students who studied 4 or more hours per day = 27.8% or 2,780 (10,000 x 27.8%)
Students who involved in a club or studied 4 or more hours per day = 53.4% or 5,340 (10,000 x 53.4%)
The probability that a student, who is involved in a club, studies 4 or more hours per day is 9.92% (35.7% x 27.8%).
Thus, the probability that a <em>student involves in a club and studies 4 or more hours per day</em> is 9.92% or <em>992 students out of 10,000.</em>

Answer:
3/32
Explanation:
Since she is putting all of the lipsticks back in the kit, that means she will always have the same "denominator" for all the probabilities.
The equation would look something like this: 2/8 * 3/8 = 6/64 = 3/32
<span>The continental crust is the layer of granitic, sedimentary and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores,known as continental shelves. It is less dense than the material of the Earth's mantle and thus "floats" on top of it.
