Answer:

3/4

Step-by-step explanation:

probability of any event = \frac{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) = \frac{number of freshmen}{total number of participants}

                                       = \frac{3}{12}

                                       =\frac{1}{4}

P (freshman is not a captain) = 1 - \frac{1}{4}

                                                 = \frac{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

marissa [1.9K]
Since Maria is going to put a trim around a triangle-shaped banner with 22 inches long per side, this means that for the banner, it has a total length of 66 inches. 66 inches would be equal to 5.5 foot. This means that the total length of the trim from the start is 7 foot. Hope this helps.
