Explanation:

Step1: Count the tally marks for Adventure books

Each group of 5 tally marks (|||| |) is 5. For Adventure books, there are 4 groups of 5 (4×5 = 20) and 1 extra, so \(20 + 1=21\)

Step2: Count the tally marks for Mystery books

There are 3 groups of 5 (3×5 = 15) and 2 extra, so \(15+ 2 = 17\)

Step3: Count the tally marks for Non - fiction books

There is 1 group of 5 and 3 extra, so \(5+3 = 8\) (but wait, no, looking at the problem's pre - filled answers, maybe we assume the user just wants to check the pre - filled numbers. But if we follow tally rules:
For Adventure: Each "|||| |" is 5. The Adventure tally is "|||| | |||| | |||| | |||| |" (4 groups of 5) plus 1, \(4\times5+1=21\)
For Mystery: "|||| | |||| | |||| | |" (3 groups of 5) plus 2, \(3\times5 + 2=17\)
For Non - fiction: "|||| | |||" (1 group of 5) plus 3, \(5+3 = 8\) (but the problem has pre - filled 8 as non - fiction? No, wait the problem's right - hand side has pre - filled numbers. If we go by the problem's structure where we just match:
Adventure: 21 students (as per the count of tally marks: 4 full sets of 5 (4×5) +1 =21)
Mystery: 17 students (3×5+2 =17)
Non - fiction: 8 students (1×5 + 3=8, but maybe the problem has a typo? No, looking at the right - hand side, the first blank (Adventure) should be 21, the second (Mystery) 17, the third (Non - fiction) 8 (but the given options have 5,17,21,41. Wait, no, re - checking the tally for Non - fiction: "|||| |||" is 5 + 3=8. But if we assume that the user made a formatting error in the tally (maybe the Non - fiction tally is "|||| | ||||" which would be 5+4 =9? No. Wait, original tally for Non - fiction is "|||||||" which is 5 + 3=8. But the problem's right - hand side has pre - filled 21 for Adventure (correct as 4×5+1 =21), 17 for Mystery (3×5 + 2=17), and if we sum 21 (Adventure)+17 (Mystery)+8 (Non - fiction)+ (Drama: "|||| | |||| | ||||" which is 5+5+4=14). Total \(21 + 17+8 + 14=60\) (matches the total given). So the numbers are:
Adventure: 21 students
Mystery: 17 students
Non - fiction: 8 students (but the problem's options have 5,17,21,41. Wait, no, looking at the right - hand side of the problem:
The first blank (Adventure) is filled with 21 (from the dropdown options 5,17,21,41. 21 is correct as 4×5+1 =21)
The second blank (Mystery) is 17 (3×5+2 =17)
The third blank (Non - fiction) is 8 (but not in the options. Wait, no, re - check the tally for Non - fiction: if it's "|||| ||||" (two sets of 4? No, tally is groups of 5. Wait, no, standard tally is "|||| |" (5). If the Non - fiction tally is "|||| ||||" (assuming each "||||" is 4, but no, tally is "|||| |" (5). Wait, maybe the user made a mistake in writing the tally. If the Non - fiction tally is "|||| | ||||" (1 group of 5 and 4, 5+4=9? No. Wait, original problem's right - hand side:
"students chose adventure books as their favorite of book" →21 (from tally: 4×5 +1)
"students chose mystery books as their favorite of book" →17 (3×5+2)
"students chose nonfiction books as their favorite of book" →8 (1×5+3) (but in the given options on the right - hand side (the dropdown), the numbers are 5,17,21,41. So maybe the Non - fiction tally was mis - written. If we assume that the Non - fiction tally is "|||| | ||||" (5 + 4=9? No. Alternatively, if the Non - fiction tally is "|||| | |||| |" (two groups of 5? No, the original left - hand side shows Non - fiction tally as "|||||||" which is 5 + 3=8. But since the problem's right - hand side has pre - filled numbers (Adventure:21, Mystery:17, Non - fiction:8 (but 8 not in options. Wait, no, re - check the problem's right - hand side. The user interface (from the image) has a dropdown for the first blank (Adventure) with options 5,17,21,41. 21 is correct. The second blank (Mystery) has the same options, 17 is correct. The third blank (Non - fiction) - maybe it's a typo in the problem's tally. If we assume that the Non - fiction tally is "|||| | ||||" (but that's 5+4 =9. No. Alternatively, if we ignore the Non - fiction (as the problem may have an error, but focusing on Adventure and Mystery as per the steps:
For Adventure: count the tally marks. Each "|||| |" is 5. The Adventure tally is "|||| | |||| | |||| | |||| |" (4 times 5) +1 =21
For Mystery: "|||| | |||| | |||| | |" (3 times 5)+2 =17

Answer:

21 students chose adventure books as their favorite type of book.
17 students chose mystery books as their favorite type of book.
8 students chose non - fiction books as their favorite type of book. (But if following the problem's dropdown options for Adventure and Mystery: Adventure:21, Mystery:17)
