A black shoe is selected at random from a bin of 6 black shoes and 4 brown shoes and not replaced. What is the probability that
MrMuchimi
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!
