Question

Tiffany has white and black shoes in her shoe box. The probability of her pulling out a white pair of shoes is 2/5. What is the chance of Tiffany randomly pulling out a black pair of shoes?

Answer 1

We know that the probability of pulling out a white pair of shoes is 2/5. This means that out of every 5 pairs of shoes in Tiffany's box, 2 of them are white. It also means that out of every 5 pairs of shoes in Tiffany's box, 3 of them are black (since there are only two options – white or black – and the probability of one of them is 2/5, which leaves 3/5 probability for the other).

Therefore, the probability of Tiffany randomly pulling out a black pair of shoes is 3/5.
