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>

The feelings of the indigenous people tend to vary a lot about this topic.
Some of the indigenous people are very hostile to any foreigners in their land, so they would not hesitate to attack, and even in some cases kill.
There are some that feel it as an usurpation of their daily lives, and do not see the tourists very fondly, but are not making any real problems, just avoiding contact.
And there are some indigenous people that actually saw a nice opportunity to modernize and make a profit of the tourists, so they are using their survival skills in the wild in their advantage, and they are very welcoming towards the tourists and encourage them to come.
