2)5/25 unlikely

3) 2/25 = 8%

I have to go so I cant finish 4 and 5 but I hope this helped

Step-by-step explanation:

1) this is based just on the results so we don't have to do any probability tree or anything. there are 25 groups overall and 19 of those 25 groups contain at least one senior. this is 76% and is over 2 thirds so it is likely

2) again this is based just on the results so we don't have to do any probability tree or anything. there are 25 groups overall and 5 of those 25 groups contain at least 2 freshmen. this is 20% and is under 1 third so it is unlikely

3)again this is based just on the results so we don't have to do any probability tree or anything. there are 25 groups overall and 2 of those 25 groups contain four students from the same grade level. this is 8% and so is  unlikely.
