Three freshmen, 3 sophomores, 3 juniors, and 3 seniors are participating on the debate team. The team's captain is randomly selected from any grade level. What is the probability that a freshman will NOT be selected as captain?

3/4

Step-by-step explanation:

probability of any event =

3 freshmen + 3 sophomores + 3 juniors + 3 seniors = 12 participants

∴the total number of participants = 12

P(freshman is a captain) =

                                       =

                                       =

P (freshman is not a captain) = 1 -

                                                 =

whenever the probability of an event not happening is being calculated, always subtract the possibility of the occurrence of such event from 1

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

good luck ! ; )

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
