Answer:
Step-by-step explanation:
In general, probably can be found as n(E)/n(S), where n(E) is the number of favorable outcomes, and n(S) is the number of total outcomes.
n(S) is the number of ways any 9 students can by picked from the audience, which is 9/140.
n(E) is the probability of picking four students from our school and five students from another school. This is (4/30)*(5/110) = 9/3300 =3/1100
n(E)/n(S) = (3/1100) / (9/140) = (3/1100) * (140/9) = 14/330
