A circular wheel is divided into 10 equal parts from the center toward the edge. Each part is labeled from 2 to 20 in increments of 2 in a counterclockwise direction starting from the top right. A needle is fixed at the center with an arrow at one end.
dan will spin this wheel once. what are all the possible outcomes of the experiment separate each answer with a comma followed by a space.

{2, 4, 6, 8, 10, 12, 14, 16, 18, 20}
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?
__
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 - 2/5 = 3/5.
So, the chance of Tiffany randomly pulling out a black pair of shoes is 3/5.
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
if a student is randomly chosen form this group, what is the chance of selecting a student with blue eyes? write your answer in the simplest form of a fraction.
__
The total number of students surveyed is:
20 (blue) + 12 (brown) + 10 (green) + 8 (amber) + 6 (hazel) + 4 (gray) = 60 students
The probability of selecting a student with blue eyes is the number of students with blue eyes divided by the total number of students surveyed, which is:
20 (students with blue eyes) / 60 (total students) = 1/3
Therefore, the chance of selecting a student with blue eyes is 1/3.
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.
__
There are a total of 10 numbers in the list. Out of these, the even numbers are: 2, 4, 10, 12, 18, and 20.
There are a total of 6 even numbers in the list.
The probability of getting an even number is the number of even numbers divided by the total number of numbers in the list, which is:
6 (even numbers) / 10 (total numbers) = 3/5
Therefore, the probability of getting an even number is 3/5.
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.
__
There are a total of 26 letters in the English alphabet.
Out of these, there are 21 consonants (all letters except a, e, i, o, and u).
Therefore, the probability of selecting a consonant is the number of consonants divided by the total number of letters, which is:
21 (consonants) / 26 (total letters) = 21/26
Therefore, the probability of selecting a consonant is 21/26.
