The mean is the average of a set of numbers. To calculate mean, you would add up all the numbers, then divide by how many numbers there are.

50 + 2 + 36 + 12 + 40 + 10 + 14 + 27 + 13 + 3 + 36 + 10 + 9 + 34 + 42 + 1 + 24 + 154 + 4 + 21 + 31 + 7 + 4 + 12 + 3 + 31 + 8 + 3 + 24 + 66 + 3 + 22 + 52 + 2 + 25 + 5 + 14 + 29 + 48 + 4 = 935

There are 40 numbers in the set, so you would divide by 40.

935 ÷ 40 = 23 15/40 = 23.375

So, the mean is 23.375.

The median is basically the "middle" of a sorted list of numbers. To find the median, place the numbers in value order and find the middle number.

1, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 7, 8, 9, 10, 10, 12, 12, 13, 14, 14, 21, 22, 24, 24, 25, 27, 29, 31, 31, 34, 36, 36, 40, 42, 48, 50, 52, 66, 154

So, the median is 14.

The mode is the number that appears the most often in a set of numbers.

3 appears 4 times in this set of numbers.

So, the mode is 3.

Mean: 23.82

Add these numbers together 1, 2, 3, 3, 3, 3, 4, 4, 4, 5, 7, 8, 9, 10, 10, 12, 12, 13, 14, 14, 21, 22, 24, 24, 25, 27, 29, 31, 31, 34, 36, 36, 40, 42, 48, 50, 52, 66, 150

=929

Then divide by the amount of numbers : 39

929/39 = 23.820512

Median: 14

Arrange the numbers is least to greatest.

Find the number in the middle of the set.

Mode: 3

Find what number occurred the most in the set.

1696 hundred thousand

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
