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?(1 point)
Since the probability of pulling out a white pair of shoes is 2/5, the probability of pulling out a black pair of shoes would be 1 minus the probability of pulling out a white pair of shoes:
1 - 2/5 = 3/5
Therefore, the chance of Tiffany randomly pulling out a black pair of shoes is 3/5.
The total number of students in the class is the sum of the number of students with each eye color:
20 + 12 + 10 + 8 + 6 + 4 = 60
So, the probability of selecting a student with blue eyes is the number of students with blue eyes divided by the total number of students:
20/60 = 1/3
Therefore, the chance of selecting a student with blue eyes is 1/3.
There are 26 total letters in the English alphabet. Out of those 26 letters, we have 5 vowels: a, e, i, o, and u.
To find the number of consonants, we can subtract the number of vowels from the total number of letters:
26 total letters - 5 vowels = 21 consonants
Therefore, the probability of selecting a consonant is the number of consonants divided by the total number of letters:
21 consonants / 26 total letters = 21/26
So, the probability of selecting a consonant from the English alphabet is 21/26.
In his class, Dale conducted a survey to observe the distribution of eye color. The results are summarized as follows:
Eye Color Number of Students
blue 20
brown 12
green 10
amber 8
hazel 6
gray 4

wrong answer try again its not 1/2 or 5/10
A letter is to be picked at random from the English alphabet. If each letter is equally likely to be selected, what is the probability of selecting a consonant? Consonants are letters except for a, e, i, o, and u. Write your answer in the simplest form of fraction.(1 point)
The total number of numbers in the list is 10, and the number of even numbers in the list is 5 (2, 4, 10, 12, 18).
Therefore, the probability of picking an even number is the number of even numbers divided by the total number of numbers:
5/10 = 1/2
So, the probability of getting an even number is 1/2.
To revise the previous response:
Out of the numbers given in the list, there are 5 even numbers (2, 4, 10, 12, 18) and 10 numbers in total.
So, the probability of picking an even number is the number of even numbers divided by the total number of numbers:
5/10 = 1/2
Therefore, the probability of getting an even number from the list is 1/2.
