To find the probability of Tiffany randomly pulling out a black pair of shoes, we first need to calculate the probability of her pulling out a white pair of shoes.
The probability of pulling out a white pair of shoes is given as 2 to 5. This means that out of a total of 2+5 = 7 possible outcomes (2 white shoes and 5 black shoes), there are 2 favorable outcomes (white shoes).
Therefore, the probability of pulling out a white pair of shoes is 2/7.
Since there are only white and black shoes in the shoebox, the probability of pulling out a black pair of shoes can be calculated by subtracting the probability of pulling out a white pair of shoes from 1:
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 - 2/7
Probability of pulling out a black pair of shoes = 7/7 - 2/7
Probability of pulling out a black pair of shoes = 5/7
Therefore, the probability of Tiffany randomly pulling out a black pair of shoes is 5/7.
Tiffany has white and black shoes in her shoebox are probability of her point out. A white pair of shoes is 2 to 5. What is the chance of Tiffany randomly pulling out a black pair of shoes?
