In: Statistics and Probability
The board of directors for Southern Alberta Insurance Company has 8 members.
(a) If a committee of 3 is formed by random selection, what is the probability that it consists of the 3 wealthiest members?
(b) If the board must elect a chairperson, vice-chairperson, and a secretary, how many different slates of candidates are possible?
If also, you could show your work, and help me understand why I would appreciate that too. Thank you!
a)
here number of ways to pick 3 member from 8 =(8C3) =8!/(3!*5!) =56
number of ways to pick 3 from 3 wealthiest =(3C3) =3!/(3!*0!) =1
therefore probability that it consists of the 3 wealthiest members =1/56
b)
number of ways =N(for chairperson 8 choices, for vice-chairperson remaining 7 for secretary remaining 6 choices )=8*7*6 =336
