What is the median of the data set? 42 55 27 31 17 24 65 47 39 18 a. 21 b. 35 c. 17 d. 24

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

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
