Tiffany has white and black shoes in her shoe box. The probability of her pulling out a white pair of shoes is 25 . What is the chance of Tiffany randomly pulling out a black pair of shoes?(1 point)

Answer 1

The probability of pulling out a black pair of shoes can be calculated as 1 - P(white pair of shoes).

P(black pair of shoes) = 1 - P(white pair of shoes)
P(black pair of shoes) = 1 - 0.25
P(black pair of shoes) = 0.75

Therefore, the chance of Tiffany randomly pulling out a black pair of shoes is 0.75 or 75%.

Answer 2

Tiffany has white and black shoes in her shoe box. The probability of her pulling out a white pair of shoes is 25 . What is the chance of Tiffany randomly pulling out a black pair of shoes?(1 point)

Answer 3

If the probability of pulling out a white pair of shoes is 0.25, then the probability of pulling out a black pair of shoes would be 1 - 0.25 = 0.75 or 75%.

Answer 4

A number from the list {2, 4, 5, 7, 9, 10, 12, 15, 18, 20} is to be picked at random. What is the probability of getting an even number? Write your answer in the simplest form of fraction.(1 point)

Answer 5

There are a total of 10 numbers in the list. Out of these numbers, the even numbers are 2, 4, 10, 12, 18, and 20, making a total of 6 even numbers.

The probability of getting an even number can be calculated as:

Probability of getting an even number = Number of even numbers / Total number of numbers
Probability of getting an even number = 6 / 10
Probability of getting an even number = 3 / 5

Therefore, the probability of getting an even number from the list {2, 4, 5, 7, 9, 10, 12, 15, 18, 20} is 3/5.
