您住的是黑人大学

校园吗？从以下统计数据可以看出除了黑人大学最有可能以外，绝大部分美国大学没有一个新的爱滋病例，更别说像MIT这种大学了。

7000 x 0.31=2170 (heterosexual sexual activity)

2170 x 0.681 = 1478 (percentage of students enrolling in college)

1478 x 0.63 = 931 (black college students)

1478 x 0.37 = 547 (non-black college students)

美国总共有4084所大学，把547人非黑人的爱滋中枪者以最广的方式分布，就是一人一所学校。那么4084 - 547 = 3537 学校根本没有任何新的爱滋病例。在两千一百万大学学生中，547人占的比例是0.0026%。以下是计算根据和来源网站。
