Answer 3

I think it is c. not sure though....

Answer 4

Im heading on B cause of 1st student can chose any of the 8; then the 2nd can choose 7 of the 8; etc.
prob is (8/8)(7/8)(6/8)(5/8)(4/8)(3/8)=.0769.

so prob that at least 2 select the same butterfly is 1-.0769=92.31

Answer 5

So you mean C. because C. is 92.31% lol
