Answer:</h2><h2>The theoretical probability of four students from your school being selected as contestants out of 8 possible contestants spots =
![\frac{14}{165}](https://tex.z-dn.net/?f=%5Cfrac%7B14%7D%7B165%7D)
</h2>
Step-by-step explanation:
The number of students participated = 30
Total audience = 150
By probability , to find the solution =
where n(E) is the number of favorable outcomes,
n(S) is the number of total outcomes.
n(S) is the number of ways any 8 students can by picked from the audience= ![\frac{8}{140}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B140%7D)
n(E) is the probability of picking four students from our school and five students from another school.
n(E) =
= ![\frac{16}{3300}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B3300%7D)
=
= ![\frac{14}{165}](https://tex.z-dn.net/?f=%5Cfrac%7B14%7D%7B165%7D)
