How the hell do you answer this question? I was absent the day my teacher taught this and I have no clue... T_T I have a test tomorrow! Help is appreciated :cheers:

2. A 5-committee is to be chosen from 4 teachers and 4 students. What is the probability that

a) there is only one teacher on the committee?

b) the students out-number the teachers on the committee?

Are you in a semestered school? Why is it that I learn nothing like this and instead am constructing pie graphs, making thesis questions and thinking of bias in my Data class *hits head against wall for thinking this would be another easy math course*

a) total number of ways of choosing 5 ppl out of 8 = 8 C 5

total number of ways to choose one teacher = 4 C 1

total number of ways to choose four students = 4 C 4

total number of ways to choose and rearrange one teacher and four students = (5C1)(4C1)(4C4)

P(one teacher and four students) = (5C1)(4C1)(4C4)/(8C5)


b) p(five students) + p(four stdents, one teacher) + p(three stdents, two teachers)

use same method as a), too lazy to do it.


EDIT - bold
