Answer:
0.245
Explanation:
Probability is the chance or likelihood that an event will occur.
Probability = Expected outcome of event/Total outcome of event
Since we are to find the probability that the selected student is going on the field trip given that the student is an eleventh
grader;
The expected outcome of event will be 13 as located on the table.
Total outcome of event will be the total number of students that went for the field trip.
Total outcome = 12+9+13+19
Total outcome of event = 53
Probability = 13/53
Probability = 0.245(to nearest thousandth)
