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?

Answer:

3/4

Explanation:

probability of any event =
(number of favourable outcomes)/(total number of outcomes)

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

∴the total number of participants = 12

P(freshman is a captain) =
(number of freshmen)/(total number of participants)

=
(3)/(12)

=
(1)/(4)

P (freshman is not a captain) = 1 -
(1)/(4)

=
(3)/(4)

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