Tiffany has white and black shoes in her shoebox 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?
The probability of Tiffany pulling out a black pair of shoes can be calculated by subtracting the probability of pulling out a white pair of shoes (2/5) from 1 (total probability):
1 - 2/5 = 5/5 - 2/5 = 3/5
Therefore, the chance of Tiffany randomly pulling out a black pair of shoes is 3/5.
