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
To determine the credibility of an academic writing one has to take some steps, this include:
1. Checking the credentials and the affiliations of the writer from the written paper. This will allows you to know if the author has an authority by means of his qualifications to write on a particular topic.

The physiologic factors that affect motility of food in the stomach and small intestines is :
- The abnormalities in the muscle.
<h3>What
cause stomach motility?</h3>
Genes are known to often play a role in in some cases of gastric motility disorders and it is seen in Hirschsprung's disease, intestinal pseudo-obstruction, and others.
Note that Weak contractions of the small intestine are as a result of the to issues in the muscle and are known to be linked or associated with diseases e.g. scleroderma.
Note that connective tissue disorders can lead or cause damage to the intestine and as such, the physiologic factors that affect motility of food in the stomach and small intestines is the abnormalities in the muscle.
