There are C(29, 4) = 29!/(4! (29 - 4)!) ways of selecting any 4 students from the total 21 + 8 = 29 students.
The teacher has C(21, 2) = 21!/(2! (21 - 2)!) ways of picking out 2 sophomores and C(8, 2) = 8!/(2! (8 - 2)!) ways of picking out 2 freshmen, so there are
C(21, 2) • C(8, 2) = 5880
possible ways of picking out 2 sophomore and 2 freshmen.
The probability of picking out a group of students like this is then
C(21, 2) • C(8, 2) / C(29, 4) = 280/1131 ≈ 0.2476

What is the Federal Reserve?
To guarantee that the financial system supports a strong economy for American people, communities, and businesses, the Federal Reserve actively participates at home and abroad and analyzes financial system vulnerabilities.

The Federal Reserve must operate within the parameters of the general goals of established economic and financial policy, which are under the control of the U.S. Congress.
Therefore, Option D is correct.
