Using the principle of probability, probability of selecting 2 students without replacement and being 11th graders is 0.230

The distribution of students :

  • 11th graders = 18
  • 10th graders = 19
  • Total number of students = 18 + 19 = 37

Recall :

  • Probability = required outcome / Total possible outcomes

Since, selection is done without replacement :

P(both are 11th graders) = (18/37) + (17/36) = 0.230

Therefore, the probability that the two selected students are 11th graders is 0.230
