Three students out of a group of 10 seniors will be chosen to speak in front of the school. what is the probability that ben, mark, and ty will be chosen

3 out of 10

hm, if order does not matter
then it is 3/10 that one of the 3 is chosen
assuming that one was chosen, we now have a probablity of 2/9
then the last is 1/8

so the ending probablity will be 3/10 times 2/9 times 1/8 or 6/720 or 1/120

the probablity will be 1/120

if the order does matter then it is
1/10 times 1/9 times 1/8 or 1/720 because there is 1 choice for each

Iwould say rat and vsu but i’m not 100% sure
