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

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
