The question is not complete, so i have attached it.
Answer:
Probability ≈ 0.245
Step-by-step explanation:
The question says we should find the probability that the selected student going on the field trip is an eleventh grader.
Now, from the image attached, the number of eleventh grade students going on the field trip are 13.
Also, total number of students going for the field trip from all grades is;
Total no. = 12 + 9 + 13 + 19
Total no= 53
Now,
Probability = Expected outcome of event/Total outcome of event
Thus,
Probability = 13/53
Probability ≈ 0.245
