Hello,
If 1 black shoe is selected from a bin of 6 black shoes and 4 brown shoes and not replaced, then there are 5 black shoes and 4 brown shoes remaining. To find the probability that the a black shoe will be selected out of 5 black shoes and 4 brown shoes, we divide the number of black shoes over the total number of shoes (Each selection of a shoe is independent).
Doing this, we get 5 / (5+4) = 5/9 ≈ 0.55
The probability that a second shoe selected will be black is 0.55.
Hope this helps!
