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 thechance of Tiffany randomly pulling out a black pair of shoes?
Since there are only two possibilities (white or black), the probability of pulling out a black pair of shoes can be found by subtracting the probability of pulling out a white pair from 1:
1 - 2/5 = 3/5
Therefore, the chance of Tiffany randomly pulling out a black pair of shoes is 3/5.
To find the probability of Tiffany randomly pulling out a black pair of shoes, we can subtract the probability of her pulling out a white pair of shoes from 1.
Given that the probability of pulling out a white pair of shoes is 2/5, the probability of pulling out a black pair of shoes can be found using the following equation:
Probability of pulling out a black pair of shoes = 1 - Probability of pulling out a white pair of shoes
Probability of pulling out a black pair of shoes = 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.
