Answer:

  • 0.0684 or 6.84%

=================

Firstly find the number of students:

  • 112 + 35 + 18 + 98 = 263

The number of students who walks to school and lives more than 2 miles from the school:

  • 18 - from the top-right cell of the table

Required probability is:

  • P = 18/263 = 0.0684 or 6.84%
