Answers

  1. Answer:
    2 Six graders: 6/55 chance
    2 Seventh graders: 21/55 chance
    Step-by-step explanation:
    Total: 11 students
    6 graders: 4
    4/11 for first student and 3/10 for second
    4/11 * 3/10 = 12/110 = 6/55
    7 graders: 7
    7/11 for first student and 6/10 for second
    7/11 * 6/10 = 42/110 = 21/55
