Question

Answer 1

HELP ME!!!!!!!!!

Answer 2

let's break this down into two parts:

- probability that he pulls out either a black or brown sock
and
- probability that he pulls out a white sock (after putting the first sock back)

for the first step, simply calculate (black + brown socks) / (total socks)

for the second step, calculate (white socks) / (total socks). since there is replacement, the total socks should not change between the two steps.

then multiply the two fractions together. simplify as needed.
