The probability that a college student is involved in a club and studies 4 or more hours per day is 9.92%.

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 student involves in a club and studies 4 or more hours per day is 9.92% or 992 students out of 10,000.

Question 6 1 pts Natural cracks in rock that form due to exhumation of deeply buried rock are called salt wedges. clasts. faults

avanturin [10]

Natural cracks in the rock that form due to the exhumation of deeply buried rock are called salt wedges.

Answer: Option 1

Explanation: 

The process of exhumation in the discipline of Geography refers to digging up of a buried rock due to natural forces applied on the surface under which the rock is buried. At a salt wedge, a river flowing with a great velocity meets the ocean where the ocean is comparatively calm.

The fast-flowing river water acts as a digging force and carries out the process of exhumation of the rocks at the wedge. The same fast-flowing water creates cracks in the exhumed rocks.
