Is this correct? i’m very confused on if my answer is right.

i can't see the whole question, but based on what I see it is right. just make sure to simplify your probability so that 2/4 is 1/2

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
