The answer is C. Mono refers to one while poly refers to multiple. Hope this helps :)
I would have to say A. All answer choices are hazardous risks
number of different pairs the teacher can choose= nCr (18+14, 2)=496
no. of opposite gender pairs possible= 14 (since there are only 14 boys)
probability = 14/496= 7/248
D is the answer your looking for
A hero is someone who inspires you. Someone you can look up to. Someone who always tries to do the right thing all the time. Like a police officer or a fireman. Heck, even a teacher. Personally my hero is Dead Pool because he's funny. But if I'm being serious my real hero is the ones who risk their lives to recue the little kittens and puppies everyday and give them a loving furever home. :D
