Answer

Explanation:

Step1: Recall probability rule

The sum of probabilities of all possible outcomes is 1. Here the two possible outcomes are pulling out white - shoes and pulling out black - shoes. Let (P(W)) be the probability of pulling out white shoes and (P(B)) be the probability of pulling out black shoes. So (P(W)+P(B) = 1).

Step2: Substitute given value

We know that (P(W)=\frac{2}{5}). Then (P(B)=1 - P(W)). [P(B)=1-\frac{2}{5}=\frac{5 - 2}{5}=\frac{3}{5}]

Answer:

(\frac{3}{5})
